He was known as "The Lone Beagle".
However, the shooter in this case is in serious trouble and from what I've read, rightly so. If it's true, a 'finishing shot' goes quite far beyond any reasonable definition of self-defense.
Yep. Minnesota has a long history of coddling criminals and punishing those who attempt to defend themselves. Especially if you do it "wrong". "Wrong" being whatever hyperbole and trial by public opinion/lynching the DA and the Red Star can drum up.
