Kyle Rittenhouse: Self Defense? | YIP Institute
Here's Kyles problem...
"Kyle's self defense claim is not supported by Wisconsin law. In fact, Wisconsin is one of twenty-two U.S. states that does not have the “Stand your Ground” law. Even in the states where “Stand your Ground” is law, the right applies to self-defense inside one's home, vehicle, or business. In those states, one can generally use lethal force without having a duty to retreat. In any event, the self-defense argument would not have applied to Rittenhouse who had already overstepped his legal framework by using excessive retaliatory force. He was an active shooter who had not complied with Wisconsin State Law, and was posing an immediate threat. After killing Rosenbaum, Rittenhouse had become an “active shooter” and all those who tried to neutralize or attack him were, therefore, legally justified in doing so. The laws sanction bystanders’ efforts at disarming or neutralizing an active shooter, especially since in so many violent instances--i.e. Sandy Hook Elementary School in Connecticut or in Parkland, Florida--attackers have inflicted great harm on innocent citizens."
In other words, what you see depends on where you sit - and the law is def not on his side.
