I listened to the press conference by the OC E Division. I thought he handled it well. It seems many of the injured were comparatively minor and not gun shot wounds but a variety of injuries as a result of the panic.
Apparently the police had been involved with the shooter for several years, primarily for wellness/mental health calls, but not in the past year. She had apparently dropped out of school four years ago.
Sometimes you wish you could just slap some media upside the head. One asked why the police "were hiding" the fact that the shooter was transgendered. He said they weren't hiding it - they were using the gender the shooter identified as (she was born male). And of course questioning why did or did not know something; less than a day into the investigation.
I don't know how many RCMP members are in Tumbler Ridge but I doubt many would have been on duty at the time and, given the geography, specialized services and backup were probably a long time coming. The first members responding were confronted with active gunfire.
