Then why do so many of us on this side of the pond read stories in the Brit press about homeowners charged when they off a perp?
Very, very few (two to my memory in the last 15 yrs), and both were deemed to have grossly exceeded legitimate self-defence.
What Americans read perhaps is that UK people in such incidents get arrested, which seems backward and unfair, but its police procedure to ‘arrest’ everyone involved for a few hrs until the facts are ascertained, what US media ignores is that the homeowners are released within hrs, after their proof of self defence is established.
