I strongly respectfully disagree. People who know guns can tell the difference between a .22 or .45, etc. In fact my post said that looks like a 9 or 45 right off the bat due to the shape and size. Am I right for sure? Of course I can't say that for sure. Ive been to various gun shows. I lived in Texas. I've shot various caliber guns in the woods....respectfully, I'm not sure why someone being able to possibly identify a type of gun is so inconceivable.
Re: the tattoo? A poor comparison. A tattoo does not have a 3d shape which leaves an imprint through the jacket.
No one said it's inconceivable that someone can identify a 'type' of gun, though 'type' could mean anything in a guns discussion, so I'm not sure what you mean.
What's been said is that the picture is so poor, and the clothing and whatever else he might have on his person is so layered and obscure, to claim it's 'looks like' a 9mm, or now maybe a .45, or a "Glock", is not consistent with the poor view that we have, or, the nature of guns.
The physical appearance of a gun tells you nothing about the bullet it's discharging. There are standard (physical) handgun sizes, sizes for C and C, and overall, the specs of a gun in all its physical and performance characteristics are too numerous to talk about with any relevance to this case.
My son was a Gunner's Mate in naval special warfare and has been to real gun shows in Afghanistan. And in regard to personal defense, we have spent many hours at a time discussing height, length, hand grip, and on and on...and on, because guns are that varied. There can be a two inch difference in just the height alone of same caliber hand guns. Etc. Etc. Etc. So he would raise his hand as someone who 'knows about guns' and say flatly that there is no way to know the specs of any gun this person may or may not be carrying, based on an outline.
Why does this matter? Not only is it unfounded speculation, I know a very tragic story about someone who thought he knew about guns and how people who carry them think, and so on, and his speculative remarks in a crisis led to police viewing an innocent person as a suspect.
I'm not arguing that this person is innocent. What I will say is that if he had a gun, what size it was physically, what diameter the bullets, or whether or not he holstered doesn't even matter. If he is the person who killed these precious children, he needs to be swiftly caught because a claim I
am willing to make is that he will do this again. And again. And my guess is, he will use anything to access and corner and successfully subdue his victims.
