I believe that there are about 20,000 homicides per year in the U.S. 9/11 to present about 100,000. Forty percent by illegals killing 'Mericans sounds high. Not impossible.
Nah, it's pretty impossible. For example, around here in Maryland, while there is a good sized and growing population of Central Americans who are almost all illegal, the overwhelming majority of the murders are committed by blacks.
