Do people pull the race card too much?

I've noticed quite a bit that people in general pull the race card too much, but which race pulls the card the most? During the course of my life, I've gathered that African-Americans pull it the most, with Caucasians in the close 2nd.

After watching the movie 'Crash', I noticed that Chris Bridges 'Ludacris' mentioned something about how black people are blamed for crime & murders more than white people. There was a segment I watched in the news last month about how the Dallas police officers and Irving police officers tend to pull black people the most and give them their "routine shake down."
