It’s always helpful to actually know what you’re talking about before you open your mouth.
When the police pull you over for a traffic stop, they will usually run you through the system to see if you have any outstanding warrants. The new Arizona law requires the police to also check your immigration status if the officer believes there is probable cause to believe you are in the country illegally. For example, if the cops pull over a guy who speaks no English and has no driver’s license, this is a clue that he may be an illegal alien. The new law does not give the police authority to just stop people for no reason, or because they look hispanic. Arizona law prohibits racial profiling.
So when your hysterical liberal friend starts screaming about racism, and people needing to carry papers like it’s Nazi Germany, ask them if they’ve read SB 1070. Odds are they haven’t.
