So if the PD comes to my door, how much will reciting the second amendment to them help me? I doubt it would help much at all.
More than likely, I would not even open the door and yell at them from my second floor window to come and get them or pound sand. I somehow doubt they will go busting down my door knowing full well what awaits them up the stairs.
If they tried to enter your home, without a warrant, or confiscate your weapons without a warrant, then under every case I know of that has set precedent, you have every right to fire upon them. I also truly believe they’d have no case against you in court, as they unlawfully entered your home. The problem is surviving the initial gunfight.
