I have been pulled and removed from my car just as you did, I was in the wrong place and statistically speaking they had a great chance of finding a white guy selling drugs based on where I was and when I was there. I was polite, accomodating, I followed exactly way at they told me to do, I was there for an hour while they brought in a drug dog.
When all was said and done they explained why I was stopped and apologized. Instead of being a beliggerant dumbass with a chip on my shoulder and escalating everything, I acted like I actually have an iq above 80 and kept my mouth shut and followed instructions. I got the guys name and badge, got me out of 2 subsequent speeding tickets.
