Nonverbal communication exists. Breaking into someone's house, especially at night, is telling the people inside, "I'm rape to rape or murder you."

Sorry, but victims have a right to defend themselves. They have a right to use lethal violence to defend themselves. You break into someone's home and threaten the life of another? Getting shot is perfectly proportionate. "Grossly disproportionate" my ass. Lethal violence is a perfectly proportionate response to rape and murder.

You also shouldn't cross the road when the pedestrian light is red

there are laws that specifically state that. there are also laws that specifically protect pedestrians and give them the right-of-way.

there are laws in place that specifically state not to break into homes. there are no laws that protect people from burglarizing a home. this is why damages are usually considered a "civil matter" because it's a disagreement between two parties that do not interest the general public.

if you don't want to be shot, don't force your way into places where you will be shot, the law and public opinion will not be on your side.
