But for some reason, the officer figured something was wrong. Maybe it's because you don't look like the people in that particular neighborhood. Or maybe the car you're driving looks a bit too expensive. Or maybe it's a rust-bucket with a damaged fender. Whatever, the cop has decided to check you out.

Particularly if you're white. Which, in a nutshell, is why folks are so upset about racial profiling. Racial profiling is the term for when certain law enforcement types determine race can be used as a factor in determining who is and is not a suspect for crime. The most common example is when African-American or Latino drivers are pulled over for questioning or search based on the assumption that minorities commit a disproportionate amount of crime. On the other, it's an infuriating situation for the vast majority of law-abiding people of color forced to accept being treated like potential criminals, often based only on how they look.
