In fact, if your 30,000,000 illegal population figure are correct, That
works out to 290 violent crimes per 100000. Considerably less than the 476

The statistics I've seen support what you've stated, and even for crime
overall (violent and nonviolent), illegals seem to commit them at half
the average rate. Actually they may be even better than that, once you
consider that they're more likely to live in high-crime areas.

Doesn't it occur to him that illegals have a very strong economic
incentive to stay out of trouble? The typical illegal from Mexico
just wants to work here for ten years and then go back to Mexico and
live in a nice house staffed by a maid and nanny. Maybe 5% of them
already have maids back home.
