As for staying or leaving, it depends upon whether my father lives. I will have to stay as long as he lives. He won't leave, can't leave. I'm close to full retirement myself so I may stay anyway. If worse comes to worse, I will defend myself with lethal force against all who commit aggression against myself or my property regardless of any badge. In this day and age, you can't really make assumptions anyway because so many wear a uniform but aren't really cops, but use the color of law and the deception of their position to commit crime (not that police aren't also criminals).
I'm not in the UK though, left defenseless against a monopoly of force with government guns. I suspect that's their main reason behind the gun grab (especially in the US), because they've been unable to curtail the grifting of the banking cartels and will soon have to resort to bail ins. When that happens, guns in school and guns in church, will likely become "guns in banks" as defrauded savers who've lost their savings feel like they have no other recourse than to shoot and hang bankers who've swindled them out of their money.
