With the exception of the UCR that's an impressive list of slanted sources. The mission statement of two of them flat out tells you they're not non-partisan. I was surprised to see the Cato institute on that list. That takes some balls to try and pass them off as non-partisaned truth seekers give their past and current share holders.
The American Immigration Council link was the most humorous. That link doesn't differentiate between legal and illegal immigrants in their data. Walter Ewing is about as far from non-partisaned as you can get and his "research" generally reflects that. I love how his sources are his own research. He never has an answer for why illegal immigrants represent crimes far more disproportionate than their population, he'd rather manipulate statistics to prove his ideologies.
