Let us decode Nadlar's meaning:
armed persons crossing state lines = A person who was not actually armed when they crossed state lines, and was actually a local living very close and spending much of his normal time on both sides of the state line.
Looking for trouble = Looking to help people devastated by violence, arson, and looting by cleaning up damage, preventing fires, and rendering emergency first aid.
People engaged in First Amendment rights = People destroying property, looting, burning, and attacking innocent targets they don't like with trailor hitch chains, firearms, and stomping on peoples heads and slamming skateboard into peoples heads. And running down Rittenhouse like a mob of blood thirsty jackals as he tried to avoid trouble and get to the police.
And don’t forget that when the prosecutor asked what Rittenhouse meant by calling Kenosha “my community” he answered, “My father lives here.”
