A little off topic but I've always wondered what if a criminal painted bright orange on the tip of a real gun? Seems to me like the police would be concerned with whether or not the orange tip on any gun is really meaningful.
My cop brother told me that he could care less whether or not the gun has an orange tip. If he orders someone to put down a weapon of any type and they choose not to, well, he's sure that HE is going home that night.
