WATCH: MSNBC’s Joe Scarborough spreads lies about Rittenhouse case

"Here we have a 17 year old kid, underage, said he bought an AR 15 because he thought it was cool. He drove across state had his mother driving across state lines, he appointed himself a militia member."

During the trial of Kyle Rittenhouse last week, the prosecution went after why Rittenhouse decided to purchase the AR-15. In part, he said it was cool looking, but it was also allegedly one of the limited options at the gun store that they went to, and it was the gun that his friend also had.

Rittenhouse was also not part of a "militia." Rittenhouse said he had gone to Kenosha in part to clean up graffiti, and also to protect a number of Car Source lots from rioters.

"He goes around and he ends up unloading, what, 60 rounds, kills two people, wounds a third person," Scarborough continued.

Rittenhouse did not unload 60 rounds. He possessed just one clip of 30 rounds of ammo. Rittenhouse fired at least 8 shots, four at Joseph Rosenbaum, and another four during a later incident that killed Anthony Huber and injured Gaige Grosskreutz. He did not reload or use additional ammo other than what was already loaded in his gun.

"This is behavior that we, and I say we, I'm talking about conservatives, liberals, gun right supporters, gun control supporters, we as a society, this is behavior that we as a society want to discourage. So the question is what law is in place so Rittenhouse and Rittenhouses in the future don't say, 'hey, you know what? Hell's breaking loose across the border in Georgia. I'm going to get my AR 15, skip school on Friday, and go up' and I'm saying though, if you're in Florida, I'm going to go across and I'm going to go into Georgia, and my teenage kid is going to just start waving around an AR 15," said Scarborough.

"None of us, none of us want this sort of behavior. So what's the charge against him for that? What's in the law that prevents that sort of that sort of activity from taking place in the future?" he continued.
