It would be interesting to see what would happen should they try to arrest someone here (US) and the homeowner came out shooting ... mistakes have been made by our own LEO’s going to the wrong home as well ...

I don't think they are armed unless we give them to them in the case of a raid. But I may be wrong about that. I have not followed this issue in years.

If a homeowner did what you suggest, they would not have protection unless LEO was with them in any case.
