At 1:44 his own video (https://www.youtube.com/watch?v=oponIfu5L3Y) says "well, I know why narcotics" regarding the warrant. So I think he'd be OK with that statement of opinion.

If that was defamation, warrants like the one in this case are defamatory, having asserted he kidnapped someone.

Of course it's not defamation. But that's not what you said. You said "seems fair"
