I'm going to echo what I've told others.
I don't think that Rittenhouse is by any stretch of the imagination, a hero. What he did was very foolish. Brave maybe, but very foolish. He is no hero. There was nothing heroic about what he did. He got himself isolated, exposed, and with very little idea of how to handle the situation he found himself in.
And by an even greater extent, Rittenhouse is no murderer. He was foolish to have driven across state lines to try and get involved, but he did not create the dangerous situation. It was thrust upon him. And from where things went south, Rittenhouse did everything right. He restrained himself in the use of deadly force to only targets that were actively attacking him--after he had chosen to disengage as safely as he could. His attackers were nothing more than common thugs who earned their reward.
Honestly, this shouldn't have even gone to trial. And yet we are better off for it. This shows us that yes, you can defend you and your own, you can do so and get a fair hearing. No matter how MSNBC tries to pressure jurors into convicting your ass. And that is why, I imagine, the left media is so furious. It will embolden people to use deadly force to protect themselves and others. As well it should.
