Immigration Laws

I don't know a whole heck of a lot about AZ's immigration law.  I know enough to get by, which is probably more than the average person does.  But I'm no expert on the law and have a lot of qualms with it.  Yet this is one part I agree with: "Brewer is cheering the the Court’s decision, arguing that the justices preserved the “heart” of the law which “lets police check a person’s immigration status while enforcing other laws if ‘reasonable suspicion’ exists that the person is in the United States illegally."

I come from a long family line of police officers.  And if they pull someone over for speeding and there's reasonable cause to check immigration status then so be it.  I really see nothing wrong with this, especially for border states.  Police have reasonable suspicion for a number of things.  If they think there are drugs in your car, or have a suspicion to think so, and they ask you to get out of the car and you refuse, they can legally pull you out by your ears and drop you like a hot match if they wanted to.  But they can't check to see if you are committing a crime by being in the country illegally?  Really?
