What's the difference between bias and racial?

I read an article the other day about these group of kids who attacked a latino man and the newspaper called it a racial attack. Then just yesterday I read that these 3 black men jumped out of a car and attacked a couple of latino brothers, yelling that they hated hispanics and gays and the newspaper called it a bias attack. What's the difference? |||Racial attack covers attacks based on race. Bias attacks cover any attack based on any type of bigotry (race, religion, gender, sexual orientation, national origin, skin color, etc).|||A racial attack is pretty much attacking someone because of their race... And a bias attack is pretty much influenced by a prejudged perspective.
