The justice department used the highly accurate and mathematical “central limit theorem” to do the study.

73% of illegal aliens are arrested on average 6 times for criminal activities.

To Zombie: Why do you want more crime in America?
To Bert T: Traffic violations are criminal if they involve arrests( drunk driving, hit and run, etc)

Under U.S. law, traffic violations are grounds to deny citizenship to even resident aliens(green card holders).
To Daniel: Someone I know was in a car accident with illegal aliens. It was a hit and run accident. The Mexican illegal aliens caused the crash and they had guns. The Mexicans had earlier stole the car and then ran away after the crash. The local police found the area the aliens were hiding and the police refused to go near them after they were cornered. The police knew they were armed and dangerous. The police left the scene of the crime to avoid being killed.

Illegal aliens are not afraid of our justice system. They run back across the border anytime they commit a serious crime.
