Zimmerman Bro: Twitter Tirade a 'Mistake'

George Zimmerman's brother is apologizing for his racially charged Twitter rant earlier in the week, saying it was wrong and probably bad for his brother's case, reports Reuters. Robert Zimmerman posted pictures comparing the teens who shot a baby in a stroller last week to Trayvon Martin, tweeting comments like, "Lib media shld ask if what these2 black teens did 2 a woman&baby is the reason ppl think blacks mightB risky." "I made a mistake," said Robert Zimmerman Jr. on CNN's Piers Morgan Live. "It unfortunately may not have helped George." (More George Zimmerman stories.)
