I'm Italian too, live in Italy, and I'm really sick of this ill-informed self-disparaging attitude from so many Italians. There are millions of Italians who will say "I haven't personally never been touched by this, I don't even know anybody who was personally touched by it, but I know this, because... well, just because, everybody knows it".
Are there corruption and crime in Italy? Yes, of course. But, except for some areas in the South, they are nowhere as prevalent as so many people seem to think.
