>If you use your right for Castle Doctrine (defend yourself), are you still arrested by the police for Murder? Generally, yeah. You just have the opportunity to present evidence exonerating yourself, whereas otherwise you don’t have that opportunity (because you weren’t). Some places even have laws that explicitly let you kill cops (IF THEY ENTER YOUR PROPERTY ILLEGALLY), but that’s a very, VERY hard one to prove and totally out of your hands (it’ll hinge on whether their warrant was legal, and judges almost universally declare that to be the case, even when it’s not).
