lemmie just state now that I'm not trying to be argumentive and that I actually think this is an interesting idea
. That's probably the reason I'm bothering to think about it.
But yeah. It makes sense to me that they can do stuff with a bullet because there's the bullet itself as well as a shell casing left behind. With a paintball, you don't get any of that. They'll just shred. I suppose the point about narrowing suspects is a good one, but they'd have to find some other kind of concrete proof to actually nail them.
