The problem is, the Law has nothing to do with Justice...It’s about assigning fault and punishment. The local County Prosecutor is an Elected position, and things can get political. For example...Let’s say I decide to help the moron holding the little girl. The other two drunk guys are just tipsy enough to charge me and my gun...so I fire a couple of shots and both drunks are wounded.
The Police come and haul me in for questioning. I claim self defense of the one guy and myself, but the County Prosecutor decides that I entered the fray as a willing participant. Why? Because in Minnesota I have a duty to retreat and I did not. I’d need a REALLY good Lawyer now to convince a Jury that I had no choice but to intervene. There is NO good outcome here for my family, me, or anyone else for that matter.

Again, very sad, but life can be pretty harsh sometimes.
