Yes, it was a senseless crime, for nothing. Nobody understands why.
It's widely reported in the media (TV, Radio, Newpaper). The dead officer is a polish immigrant and the alledged killer is a troubled and suspended RCMP officer. It's reported that the killer had previously made death threat against a church official in another province. He may have mental disorder/problem over the past few years. That may explain why he went out at 4:30am and attacked the police office without any reason, maybe just because the police officer was wearing a police uniform.
