Yeah, the kid and his friends chose to travel to a place where they believed there would be a riot, and protect someone's business, which meant apposing a mob. And the chose to be armed to do so. They also apparently chose to split up enough that one could be attacked and the others were unavailable to help. The outcome was a string of self defense encounters. But it was not unforeseeable.
I know you're angry that law enforcement was told to stand down. But I already address my belief as to why that was done. You can feel free to disagree with it all you like.
The Rittenhouse situation was one of bad tactics as opposed to bad morals. NONE of them EVER should have been alone, much less alone in crowds of rioters. Whomever Rittenhouse was affiliated with let him down, BADLY.
When the government ignores or takes the side of the mob, countervailing centers of power will develop.
In 1919, White supremacists tried to burn down Chicago's Black community. The police took the side of the rioters and arsonists. My great uncles, just back from segregated service in France, stepped in with other members of the community, broke into their National Guard armories, armed themselves and fought back. If they hadn't, I might not be here to type this.
Likewise, when government gives wouldbe Spartacists a free hand, a Freikorps will INEVITABLY arise to oppose them.
I don't CARE why the government in Kenosha abdicated its duty to preserve public order and safety. It only matters that they DID. The police have no legal duty to protect individuals. They DO have a duty to preserve order. If they WON'T then there is no point to their existence. If the police sit around and do nothing while they WATCH looting, arson, assaults and murders happen, others will step in. The Rittenhouse trial was the Marxist left's reaction to that rejection of mob rule.
People aren't going to allow their communities to be burned to the ground and themselves victimized, regardless of local government's cowardice or sympathy for the perpetrators. I believe that one of the Kenosha prosecutors said words to the effect of "Sometimes you have to take that beating." In Kenosha, Antifa and its allies learned that when you try to dish out that beating, sometimes you have to take a bullet.
