Ann Coulter is arguing on the other thread for urban blacks' arming themselves. She has some logic on her side.
Trayvon beat down a bus driver a few days before he went to work on Zimmerman. If that bus driver had been armed, Zimmerman might never have seen Trayvon lurking in his neighborhood.
Armed blacks -- honest people with guns -- tend to filter and thin out the thugs before they get out to prey on outgroups.
