Italians in LA live in Latino areas. Lincoln Heights was LA's Italian section in the early 20th century. There are still a lot of Italians there. A lot of Italians that came into a little money in the 40's and 50's moved out to the San Gabriel Valley. They're still there. A lot of Italian owned restaurants in the area.
Frattiano's book is a fun read, probably the best book written about the LA mob, but I believe he exaggerates about the relevance of that family. I don't believe he pushed Moe Sedway around the way he claims. I don't believe Bugsy confided in him, as he claims.
