Romanians don't normaly use violence,they work in a way that they are more the "snake in the grass" kind of character.(ie pick pockets and steeling your bag without you noticing!
The days of muggings are a few years ago now,yes we have the odd problem now and again but most of that has been cleaned up by the police and tougher penalties in the courts.
Becareful of the "gang" playing the "dried pea and wallnut" trick on the walkway and subways too.
There will always be crime,but the police have it quite controlled now,it is certainly a far more serious issue in the uk,from what i am reading on the bbc news website.
