I read where the Bad Guys will use a black marker to hide the orange tip. I'm waiting to hear of some genius painting a real gun's muzzle with orange.
I can't imagine why they would do this. Disguising a toy gun as a real one is just begging to be shot.
"I'm waiting to hear of some genius painting a real gun's muzzle with orange."
This has some validity, but I suspect a more successful camouflage would be to take a plastic bottle cap of appropriate size, paint that orange, and slip it over the muzzle. That would look a lot more like the toys than a real muzzle painted orange.
But I suspect that experienced cops wouldn't be fooled.
