This is not a political post. The UK has armed police officers. So an armed police response is acceptable within your laws and police services. Maybe my use of "off duty" was wrong, so allow me to amend my post: You are assigned to an undercover unit where you will need to be armed. This post has nothing to do with the politics of being armed.
Let me explain the purpose of my post: I am trying to get a handle on your tactical training. Your tactical thought process. I want to see if officers with military training view equipment differently than someone without military training. What I don't want is a rote political response. I want to see a discussion of risk assessment.
If you never want to carry a firearm, then do not reply to this post. I also want to avoid the standard "good copper" response of" I will use whatever my service issues." No one ever knows what threat he or she will encounter. What I want is some insight as to how an armed officer evaluates and deals with his risk assessment.
(As an aside, many of you mocked and teased Moxnil. You may not have agreed with his views, but he did not deserve to have been bullied. You can disagree without being disrespectful, and no one should be bullied.)
