Loathe to fuel any of Sarnia crazy views but a little naive. Do you imagine what it is like going to most calls knowing there is high chance that the suspect will be armed?
The problem is it is all out of control, and the police turn up often with fear in their eyes, pumped and act heavy handed out of self preservation.
All these examples listed on this thread are horrendous but saying police must observe a weapon is not practical. I have no solutions mind and violence breeds violence and no appetite for anyone to want to give up any weapons that they see as protection.
