>>So, what're the odds of someone in California getting ICE to show up in Arizona for a raid?<<
866-347-2423 is a national 800 number. Yes, a FREE CALL.
There is Freepers in Phoenix, Arizona who profess to be against illegal immigration. I am presuming they are capable of calling and making the report.
Call 866-347-2423
Don't have to be from Az to make a report.
These guys will do it for you!
