Benjamin Crump, the attorney family for Trayvon Martin's family, thanked the protesters who helped generate national attention for the case after George Zimmerman was arrested today.

"Its those young people, they believe completely in the idea of justice," Crump said at a press conference today with the family, praising them for believing "if we just stand our ground, we can make a difference."

The self-defense law that proved the basis of the initial decision not to arrest George Zimmerman is known as a "stand your ground" law, because it says that people do not have to retreat -- can stand their ground -- when they are threatened. Zimmerman does not dispute shooting Martin, but said he acted in self-defense.

Rep. Sheila Jackson Lee, D-Texas, praised Special Prosecutor Angela Corey during a CNN interview for being "willing to fight what would be the affirmative defense of stand your ground."
