Here's a few more statistics Tony somehow managed not to include in his article:

* There were about ten million illegal aliens living in the US in 2005.
* In 2003 there were 55,322 illegal aliens incarcerated in federal/state prisons and local jails.
* These illegal aliens combined for 459,614 arrests on 691,890 offenses
* On the average each illegal was arrested at least 8 times
* About 24% of these offenses (166,054) were drug crimes.
* About 15% of these offenses (103,784) were property crimes such as burglary, larceny, auto theft and property damage.
* About 12% of these offenses (83,027) were violent crimes such as murder, rape, robbery and assault.
* 80% of all arrests (367,691) occurred in three states - California (58%), Texas (14%) and Arizona (8%).
According to your numbers, one half of one percent of all illegal aliens are in jail for a crime other than being here illegally, as opposed of 1.7% of American blacks between the ages of 29 and 36 (2002 census figures).
