Are we allowed to shoot an unannounced intruder that picks the lock?
Depends. Who’s behind the intrusion matters.
Technically, “yes” in many states.
However, these lock pickers are just looking for an excuse to shoot back -— then they can make any accusation the want and there is no one left to rebut it.
Here in FL I would not hesitate.
First of all all Americans should be considered armed. That said, my conscience allows me to shoot, stab, bludgeon, strangle, drown or do whatever other mayhem is available to me in the moment to any and all armed home invaders.
If they happen to be committing their violent B&E under the color of law I may not survive or I may end up in prison but I won't for a single moment of my life feel the slightest pang of remorse.
that would be my first reaction....oops...sorry about that officer
