Oh yeah, do it! Only be careful! I had the film ripped out of my camera once when photographing in Soho (red light district) I was pretty young at the time... actually the best way to do it is set up shots with mates...then you wont get in to trouble...it wont be candid tho...I have a really neat littlecamera called a 'coolpix S4' which has a twisting lens so you can take snached shots with the camera in your lap....gots some great stuff with it...I collect cameras too,lol.xx
