Well, apparently people in the States are quite paranoid so it's hard to give advice not knowing how people react up there. Over here, there's no probs and people are actually quite curious when they see someone with a cam! I guess that helps! The only advice I can give is to have a big zoom so u don't have to put the cam in people's faces and u can pretend u're shooting something else while actually focusing on someone quite far away! ;)
