i know you can't generalize but the majority roma I've met have always been up to no good, i;ve caught a roma woman going through my bin and taking bank letters which ive shredded, she's done this multiple times on different streets. I've see roma beggars pretended to be disabled for money, seen roma kids surround a old woman and rob her and seen roma men literally sell different pavement slabs on a street for people to beg on.
