Crash

Ludicacris's character (during the beginning of the movie) was talking with his friend about how white people automatically think him a thief just by the way he looks, and the color of his skin.

The young caucasian couple (the woman mainly) was walking down the sidewalk with her husband, and coincidentally locked her arm or her hand within her husbands as soon as both her and Ludicaris made eye contact. The young man (played by Ludicaris) showed that to his friend as fear stemmed from racisim. He told his friend that she thought he was a theif/gansta and held on to her husband out of fear, not love. Ironically, the young man and his friend stole the car from that couple only a few minutes later
