That's not much of an argument in favor of Richard's position.
The law says you cannot chase after someone and then kill them blocks away from your property.
And the grounds of such a law are pretty rational.
Someone could get into an argument with someone else in a parking lot, shoot them, and then say; "I just chased this guy ten blocks from my house - I saw him casing my place!"
I’ll take the word of a heroic veteran.
