From the opencarry.com Wisconsin forum:
“There is a great deal that we don’t know and I do hope the facts support the need to use deadly force. I do grow weary of the never-ending media quotes from friends/neighbors/family in cases like this. They always imply, “he was such a good boy”. Three closed and three open cases in Wisconsin Circuit Court in the past three years for under age drinking, obstructing/resisting, bail jumping, disorderly conduct and battery don’t mean he deserved to die, but engaging in those types of behaviors definitely increases one’s risk for injury or premature death. Unfortunately this point is completely lost on the enabling friends and family.”
It was also stated that the “sun room” was locked.
Then, the homeowner has a wooden door between the kitchen and the enclosed porch (which is quite small). He said he doesn't have a key for the lock in that door so it's always 'unlocked' ~ which is part of the reason he got his pants scared off him!.
But, again, all he needed to do is leave it closed. You're not supposed to go in.
The initial problem ~ the girls next door ~ are still there.
As a sidelight to this very complex situation, the fellow who was shot is out on parole awaiting processing of four previous charges. The parole stipulates that he won't use alcoholic beverages. So, when he ran from the cops, in itself a crime, he was a fleeing felon, and he ended up in somebody's house ~ always a no-no.
Like the DA said, self-defense covered this one nicely. He thinks SYG does too but he didn't need to use it to arrive at his conclusion.
