Immigration and crime in Arizona

Interesting chart from America's Voice Online about crime in Arizona, suggesting that local-level immigration crackdowns increase crime, while crime is down elsewhere.

It is a back of the envelope type of thing that does not take any other variables into consideration (past crime rates, socio-economic status of different jurisdictions, etc.).  Regardless, it is another example of how crime cannot be used as a justification for tougher enforcement.  There is already abundant evidence that crime overall is down, and this represents even more anecdotal support.
