The Migration Policy Institute just put out a report

Collateral Damage: An Examination of ICE's Fugitive Operations Program
http://www.migrationpolicy.org/pubs/NFOP_Feb09.pdf

which, as the LA Times reports in:

Most immigrants nabbed in violent-crime sweep lacked record
http://www.azcentral.com/news/articles/ ... 04-ON.html

that only 27% of the illegal immigrants arested by ICE's fugitive operation teams actually had criminal records. (Besides violating the immigration laws of the US and, most likely, ID theft.)


Let's see: 100% - 73% = 27%.

If the sample is indicitive of illegal aliens in general, then 27% of 12,000,000 = 3,240,000 hard core illegal alien criminals roaming the country.

Interestingly, that is a number in the ball park to what other indicators reveal:
