The Gypsies that are the biggest problem are not the local ones, but those that have come from non-EU countries like Romania, and the parts of the former Yugoslavia that are not part of the EU. I think only Slovenia is a full-fledged EU member at the moment.
At the very least the Italians have the right to lock up pickpockets, scam artists and others practicing some of the better-known Gypsy scams.
Here in the US there are fortunately few Gypsies. Here in Miami they come down when it gets cold up in Jersey. They like to claim that they know how to do autobody work, which they don't. They fill dents with bondo, get a deposit and promise to return the next day, but don't.
There are also a bunch of traditional Irish and English thieves and con men known as the Travelers, who tend to have a base in North Carolina. They like to pretend that they are home repairmen, which they aren't.
