Four criminals picked the wrong Harlem shop to rob. As they tried to put plastic cuffs on two employees, beating one who resisted, 72-year old Charles Augusto Jr grabbed his shotgun. He killed one of attackers and mortally wounded the second. The other two were also hit and fled bleeding. Both were found by police and arrested. Augusto, obviously acting in self-defense, was not charged.
Had Mr. Augusto relied solely on the police for protection, rather than arming himself, at best he and his employees would have been robbed and possibly beaten. At worst he'd be lying dead, after the criminals decided it might be better not to leave witnesses. Fortunately he didn't have to find out what might have happened.
