I hear u, but all in all, I don't think a random guy who's contemplating spending a few years here is going to run into a situation where a cop mistakenly shoots him, or lets something illegal happen to him unpunished. as long as you're following the law, you're probably going to have a fine time in the USA no matter what colour you are.
Canada, New Zealand, and Australia are great I'm sure, but I'd argue the diversity you'd encounter is greater here and worth the slight chance you'll run into a tragedy like this.
why do you care so much if tourists come to the us
do u work for the tourism dept? is this astroturfing?
