"[L]ook at the total number of homicides in those years. Per the FBI, there were 67,642 murders in the US from 2005 through 2008, and 115,717 from 2003 through 2009. Per the GAO, criminal aliens committed 25,064 of them. That means they committed 22% to 37% of all murders in the US, while being only 3.52% to 8.25% of the population.
Conclusion: criminal and illegal aliens commit murder at much higher rates than all inhabitants of the US - at least 3 to 10 times higher."
