Although the evidence tends to suggest that they were, ultimately, correct:
Peterson told Kegley that he had gone to his ex-girlfriend’s house early Sunday morning in hopes of patching up the relationship after a recent breakup. He said Peterson lost control when an argument erupted and other people started ridiculing him as a “worthless pig.”
Police, who declined to provide details of the argument, said Peterson stormed out, retrieved an AR-15 rifle from his car outside and burst back into the house firing 30 shots that killed all but one of the people at the party.
I suppose one should feel lucky to only get a traffic ticket after calling a police officer a worthless pig. It’s interesting to note that a mass killing by a policeman doesn’t generate the media calls for disarming the police the way that a mass killing by a member of the public does always leads to calls for disarming the public.
I’d much rather that the public was permitted arms and the police were not. You can neither make nor keep the peace with guns, except by defending yourself. The police not only are not interested in defending you, they specifically deny any obligation whatsoever to defend you.
Moreover, courts have repeatedly upheld those denials. Whatever they are doing with those guns, they’re not defending you.
