I dunno why but the way you put it, especially the quote, it made me laugh. There aren't as many as much as in Hungary though, at least I'd think not proportionally. The thing is in Hungary there has been a massive violent reaction against gypsies, because the vast majority live off state welfare and continue to have children, so up to 8-10 kids per family quite often. So there's been a horrible backlash. However, the gypsies have done the same, often scaring tourists away and walking around in gangs of up to 200(!!!) on the streets kicking over rubbish bins, blaring music, throwing bottles in the evenings.
Also, once a roma was found on a night-time bus stabbed and murdered by a ninja sword, so the media and the Socialist Party started blaming skinheads and white extremists, and they said the rightist parties were responsible. Later the police investigation found that in fact it was another roma who had stabbed him, for refusing to pay back a loan or something.
