Registry not accessible during armed standoff

I have a prime example of why the registry is useless. My friend's house was broken into in Edmonton and there were firearms in the house. The intruder was holed up inside and would not come out. Tac team called in, snipers, grizzly apc's etc. I helped the SWAT teams with the layout as my friend was on holidays. We had to call my friend and list over the phone each of the firearms he had because the system WAS NOT ACCESSIBLE.
