Actually, in some states in the US it is legal. I just like the fact that policemen can't get away with it either where it is illegal.
Call this insulting, and some will, but part of the uphill struggle here is the ignorance of a large portion of the population. By simply ignoring the corruption and stupidity of the law, and ignoring all evidence, they make someone like me work a lot harder. Then the mess is still not cleaned up and the audience has fun dumping on me from their high and mighty position of willful ignorance. Tell me how this situation is suitable for anything except for me to dump off my own emotional baggage.
