This of course, makes the whole event un-possible. The Detroit News: New York gunman had served time for grandmother's death
After all, felons, by law, are prohibited from owning or possessing firearms.
Police in New York state say a man who ambushed firefighters had served 17 years for manslaughter in the death of his grandmother.
Webster Police Chief Gerald Pickering says 62-year-old [felonious idiot] was found dead of a self-inflicted gunshot to the head.
A real shame he didn't skip part A and just go straight to part B of shooting himself in the head, would have saved a lot of good people's lives.
Of course, the article notes you don't need a firearm to commit a horrific act:
Webster, a middle-class suburb, now is the scene of violence linked to house fires for two Decembers in a row.
Last Dec. 7, authorities say, a 15-year-old boy doused his home with gasoline and set it ablaze, killing his father and two brothers, 16 and 12. His mother and 13-year-old sister escaped with injuries. He is being prosecuted as an adult.
No a firearm isn't needed for a massacre, and good luck banning possession of gasoline.
