illegal aliens is due to the following:
“... 55,322 criminal aliens were arrested a total of at least 459,614 times, averaging over eight arrests per alien. The Department of Justice expressed its surprise at the ‘extremely high’ rate of re-arrests for criminal aliens when it found that that 73 criminal aliens in a study group were arrested a total of 429 times.”
...quoting a Government Accounting Office (GAO) study.
This GAO study is only counting the number of arrests! And that should bring two questions immediately to mind:
How many actual crimes did these 55,322 criminal aliens actually commit?
How is it even conceivable that each of these illegal aliens could be arrested on average a total of almost nine times?
But to add more insult to injury, many American cities even allow illegal aliens to obtain free health care, food stamps and a whole assortment of government goodies without having their immigration status questioned.
