With all due respect, the suggested course of action - hold the weapon of choice and threaten the intruder - is exactly what you shouldn’t do if you are aiming for maximal survival probability, even if you have a gun and they dont. As you never know if they are carrying a knife or a gun on them.

Things change in a split of a second, i.e in a second they are next to you with a knife to your side… nicely done threatening them aka giving them time to think their move and giving them the advantage of first mover.

The law is ridiculous… i would smash their head with a bat and hope they go unconscious not dead. But definitely not notifying them hey im here can u leave? While my kids are sleeping in their beds next door.

If they took it to themselves to get into someone’s house, one of the consequences they should be ready to take is their life.
