not in my house they don't. that is true in Great Britain. they expect you to retreat & not protect your belongings there. i'm not going to shoot someone just because they break in. but they had better be headed for the exit when i see them. if they know i'm there & STILL break in, the headlines in tomorrows paper will feature them & their exploits in all of the gory detail...
Doesn't matter how you deal with it if you end up in Prison. That leads back to lame laws that protect crooks. I'll drop anyone that breaks into my home while im sleeping. IMO it's assinine to wait and see if they are gonna hurt you.
