Actually, not. this guy was not an applicant, but rather a convict (well of a misdemeanor assault on a former live in girlfriend.) Also a wife killer, as well as a cop killer and grandfather killer (I'm a well armed grandfather myself).
My comment was based on incorrect info from "FromMoscow". The actual details on the suspect were very different from what was originally claimed.
Yeh - they're calling it an AK now, which certainly matches the amount of ammunition expended in that relatively short time in front of the courthouse and the lines of bullet-holes on the vehicles and structures struck. However, they're still insisting it was legally purchased, which I doubt strongly if it was, in fact, full auto as it appears. Time will tell.
That was the first Moscow LEO killed in the line of duty in around 110 years. Prayers for the family.
