A country can arm or not arm its police force as they see fit. I have no problem with that at all. In most of my area it is rural in nature and the next closest armed policeman or policewoman may be many miles away. At night there may be only two on at any time and they may be 20-30 miles away. You can do the math but a mile a minute is hard on country roads. So our armed policemen have to be armed and almost entirely self sufficient. For that reason I think the pump shotgun has become the backup gun of choice and seems to be the primary weapon after dark.
After these attacks I expect police departments the world over will be reviewing their procedures, arms in police hands and training. I hope some good comes out of this mess.
