Interesting videos. Why would anyone make that Facebook page?

Anonymous said...

And don't we all feel safe and secure because GPD is on the case. Lol

that video would be more informative and interesting if they told what each surface was.

SCATS said...

To 1:36PM ~~ I was also disappointed by the lack of that info.

11:20 If your comment was meant as a question I'm glad they are on the case as I'm sure others in our town , outside of this blog, feel likewise. Too bad you are out of touch and definately in the obscure minority regarding our police officers
Please, before you comment, I'm not police officer so don't waste your time implying that I am. I just don't happen to share your opinion which obviously differs with mine , 11:20!

SCATS said...

To 3:17PM ~~ Oh puh-leeze! You can't PROVE ANYTHING YOU SAID.

Show us the other person is "out of touch." Show us he/she is in the "obscure minority." Yeah, I know. You can't! lol

Please stop trying. Your "efforts" to minimize this BLOG are pathetic.

Anyone know -Is it possible to damage windshields using a slingshot? With stones? With BBs? With ice?

Anonymous said...

Scats. Again taking things personal. I was addressing another commenter regarding disagreement with his or her opinion period. What's your problem? Why do you go off on comments made in support of our local police? Are such comments not welcome on your blog? If so please advise , if so, and I will cease and desist .
Just for the record, I saw nothing in my post that spoke to the effectiveness or minimizing same regarding this blog in my comment. Your thoughts?

5:57 Yes! Again depending in environmental conditions and distance of travel velocity created by the device.
When we were kids, we mad them out of tire inner tubes and tree branches. However, using today's technology and available equipment, one could easily fabricate a weapon of this magnitude combined with one's arm strength sufficient to penetrate glass.
With regards to today's cars, side window glass would be most vulnerable. I doubt that the thickness of the safety glass on windshields would lend itself to penetration by medium sized stones. Here again the same dynamics involved with BB 's and pellets are involved but with one other important factor, volume. Simply stated , the larger the projectile, the more damage would result. Here again, size and weight will be a factor in distance traveled by this object and it's velocity at the point of impact, Accuracy of such a device would be seriously compromised.as well.

As a small child, maybe 4 or 5 I was shot under my eye by a pellet. I was taken to the hospital to have it removed. I didnt need and stiches and only have a small scar under my eye.. there is no was a BB/pellet could do the kind of damage reported. My guess would be a sling shot or (God forbid) a bullet.. I got hit from maybe 50/75. Feet away and like i said, i only have a small scar..

SCATS said...

To 6:31AM ~~ Why do YOU go off on those who disagree with YOUR perspective?? YOU/6/15/2014 3:17 PM personally attacked another responder & expect I'll say nothing? LMAO!

Anonymous said...

Scats, to your original question of why a bullet or BB cold penetrate "cleanly" and not a rock - I suspect it is to the single point of contact in the bullet or BB as opposed to the multiple points of contact from an irregularly shaped object. Of course the speed of the contact is important also. A tornado can push a straw into a tree, but without the force of the tornado behind it, the straw simply gets mashed. Maybe some of the engineers out there could clarify my answer further.

In response scats, why not let the person that you claim I "went off "on defend themselves, While I recognize the fact that this is your " Baby" and can do as you wish, it would be refreshing , at least to me, that you allow the person I disagree with respond and make his./ her argument in response to me without your one sided predictable interference . In so doing, you treat individuals as though they are not capable of an intelligent defense of their position If I were them , I would be insulted by that inferenence as I'm sure this person is quite able to defend and make his/ her own case. Your thoughts?

SCATS said...

To 9:29AM ~~ TY.

To 10:15AM ~~ My thoughts are that YOU CHANGED THE TOPIC from the capability of the Greece PD brought up in an OBVIOUSLY sarcastic comment posted by 6/15/2014 11:20 AM to telling that person they are "out of touch" and in an "obscure minority"! That's a PERSONAL ATTACK on him/her & completely unrelated to GPD's capabilities. Because you do NOT know that person, you are NO AUTHORITY on whether or not they are in touch, out-of-touch, obscure, relevant, etc. Capisce??

I'm really sick & tired of the PERSONAL attacks on here in an attempt to change the subject (i.e. take the heat off of??) GPD, GCSD or others that are the subject of discussion.

I'm also tired of people making totally BASELESS comments. WITHOUT supporting your contentions, you come off sounding juvenile, uninformed, and perhaps uneducated. It's getting to the point where perhaps your comments won't get posted unless you back up what you say.

EXAMPLE 1: I think GPD is doing the best they can, BECAUSE I see them patrolling the expressways & overpasses more rigorously than before.

EXAMPLE 2: I think GPD is incapable of resolving this situation because they aren't quickly establishing a secure perimeter around the scene of the shootings which allows the perp to get away.

If you can't back it up, don't say it.

I traveled on 390 last Wed, Thurs and Fri and Sat. I did not see any GPD or even state troopers anywhere. Sure, they could be in unmarked cars, but even those are usually pretty obvious. Are they using civilian cars? Maybe. Maybe not. I ducked down low in the front passenger seat and had my poor kid duck down even lower in the backseat. To be honest, I wanted to put a safety helmet on him!

And yeah, we of course could've used other roads but we needed to get where we were going quickly and I took my chances on 390. I just didn't see any police nor did my husband who was driving.

Just comments on the subject.

SCATS said...

To 11:30AM ~~ I don't think your lack of feeling safe on local expressways is atypical at the moment. I know most folks I've talked to are taking other routes if possible. Whoever is doing this is terrorizing the locals. It's the only word that fits.

Anonymous said...

@11:30 i was also driving 390 going east from Vintage at around 2:15, I saw police all over 390, at every turn around,it was also the case half an hour later while on my way home.My husband was also coming west on 390 from Avon around 5pm, and he saw the same, both marked and unmarked cars at every turn around. Im not sure what time you were driving, but we both saw local and state police everywhere.

Anonymous said...

All incidents have occurred during the week.

and the GPD vehicles I did see on 390 last week were empty. How does that deter the sniper from striking again?

Law enforcement hasn't even presented a profile after all these incidents. Where is Helpful Hank and Boy Wonder the wannabe investigator?

Sucking up to Chief Phelan which is what they are good at.

SCATS said...

To 12:22PM ~~ Obviously, they can't be there in those numbers all of the time, right? My impression is they come ... then they go ...

To 1:16PM ~~ Actually, a week ago last Saturday, there was a search for someone in a ghillie suit, followed by another report of damage on 390. Other than that, I believe the rest were during the week.

As for a profile, I have this to offer: A young Caucasian male, age 17 to 25, or so, possibly with an accomplice at times. A bit of the nerdy type - knows physics well. Think Sheldon Cooper. Probably fit, very active. Lives in the Greece/Gates area. He's either unemployed, or works evenings/nights/ maybe weekends. To him, this is a game ... him vs. the cops ... and he's winning. Perhaps he's got a bit of a vendetta against, or score to settle against the police. Possibly a paintball aficionado. He's got experience with weapons which makes him a pretty good shot, so far.

Scats, this was on Friday that my husband and I saw them all. Like I said, I saw them between 2:15-2:45ish, my husband saw them while driving 390 west coming from Avon around 5ish. Over the past few weeks Ive seen them at turn arounds and on over passes a lot as well. I dont know if they were there the whole time, but there were 2 at each turn around, from Vintage to Chili ave where i got off. I dont know how far past Chili ave they were. Is the profile you mentioned your opinion or a true profile that police have put out that I missed?

Anonymous said...

@1:16 If the cars you saw were empty, where were the police? The ones I saw had 1-2 police in each. I saw 2 cars at each turn around, mostly one marked and one unmarked, just plain black. At one spot I saw both unmarked. All had police in them tho.

Anonymous said...

Apparently Sniper has struck again. 390 at Vintage.

SCATS said...

To 5:08PM ~~ I'm not finding any reports of that. What is your source please?

Anonymous said...

@SCATS is your profile fact? I have not read or heard anything in regards to a profile of the shooter/shooter's?

Anonymous said...

Lots of speculation I see! Also no substantiated facts reported as I see it, because for every report there is one that is contradictory.
Can someone be so elusive with a long gun, in so much open territory, with no witnesses making such extraordinary angle shots? And if they're firing from a moving vehicle, how does no one see them?
My summation - No one posting has any useful data. No one can prove that a "sniper" exists. What type firearm(because that what it takes and pellet guns really can't - whether you believe an expert or not) is used. Ergo, no shotspotter reports of a firearm, and finally no traffic cam pics.

Try porcelain from a cracked spark plug as a theory. Don't even have to throw it with force according to this and about 100 other hits .
Just tossed from a passing car. All the hits seem to be on the drivers side. Found original idea/theory from a forum called yellow bullet. They are car drivers that are concerned in Rochester.
So he could drop it from a bridge or toss it at a car as it passes him or he passes it. No accomplice necessary. Just like everyone that flicks their cigarette stubs out the window.

To 6:08PM ~~ Check out 9:36PM's video link.

Anonymous said...

The accuracy and luck required for thrown or dropped objects is even less believable than the high accuracy required from an air rifle. Explain the result of porcelain debris(like the powder I would assume around the fracture and easy to spot and unreported by any agency).

Please view the following link, use common sense and then interpret the location, time and probability of the claims in each incident reported as they fit the ballistic data included.

http://www.crosman.com/university/velocity

I think you will find the energy necessary to penetrate or create the glass fractures described is not realistically possible as the energy drops drastically in very short distances.

If you insist on the theory of mobile shooter, why have no sightings of weapons been reported?

SCATS said...

To 6:10PM ~~ Do you believe we've been told EVERYTHING about the investigation?? I DO NOT! So if there was some "powder" found, I'm pretty sure neither of us would be aware.

WHO is insisting on a "mobile shooter"? Certainly NOT us. That was raised by the cops investigating.

SCATS said...

BTW, the physics lesson on velocity was a nice refresher on high school physics. However, I'm sticking with Baxter's demo and mention of "true bullets" given the many varying situationsof the different incidents.

Anonymous said...

You're have now agreed with my numerous postings and believe it is highly unlikely for pellets, bb's, or dropped/thrown projectiles to be the cause. Thanks.

But I now would like for you to please define how firearms, ejecting projectiles, fired by gunpowder, are not being shotspotted? Nor are the projectile being retrieved?

SCATS said...

To 5:49PM ~~ There are a number of potential causes that have been suggested here. How do you know what's been "retrieved"? As far as I'm aware, the cops only mentioned BBs.

Anonymous said...

Because I believe that's all they've found? Which means - barking up a wrong tree and/or hoax, which, I think, fits the current published evidence.
All rifles and pistols sold have a traceable projectile on file with the FBI. This presumes that forensic analysis can be done on those recovered projectiles given a "good enough" condition.
Again, if it's from powdered projectiles, why is there no shotspotter, nor eyewitness account? And what explanation exists that these "victims" haven't gone public with the evidence necessary to confirm my analysis above, if everyone believes the PD's are being elusive?
In this era of social media, we all know that if other evidence existed, it would be outed on FB, SCAT's, and news channels. Especially if anyone had something to gain!

SCATS said...

To 4:51PM ~~ How do you explain ALL of the broken windshields & windows if this is a "hoax?" How do you explain the involvement of the FBI, NY State Police, Monroe County Sheriff's Office and a number of local policing agencies? Whoever created this "hoax" is obviously much smarter than the sum of the investigating agencies.

What's to be gained is a $1000 reward at this point.
