Please play out the scenario for us.
Something like this?...
*smash*
<Nasty wakes up, turns over in bed, reaches to gun safe, unlocks with fingerprint scan, locked and loaded... armed in less than 5 seconds>
*Mission Impossible music as Nasty stealthily walks upstairs from his basement bedroom*
*Nasty gets eyes on menacing intruder in hallway*
Nasty: "Whoa there illegal intruder. I have you in my sights you dastardly individual. Speak now... Do you intend on stealing my TV and car keys, or is your nefarious intention to rape grammies and murder the both of us? For if it is the former, I have no intention or legal right to dispatch my loaded and cocked firearm at the centre mass of your person, however, you scoundrel, if it is the latter, prepare to die!"
You can take it from here and let us know how you'd handle it.
