There's a lot wrong here...on both sides to be fair...but he wasn't arrested for not standing for the pledge. I can almost guarantee the point where it was decided he was going to be arrested was when he started issuing verbal threats of violence.
The fact that he denies saying any of that doesn't really count as a defense. What 11 year old wouldn't lie in that situation? I'm not saying he did or didn't, I wasn't there, but if you threaten a teacher with physical violence after the police are already involved is it really surprising when you get arrested?

A more sane approach would have been to not let it escalate, let the kid sit,
I would add to this part that the substitute teacher never should have asked the child to stand. DT is right, the Supreme Court resolved this issue years ago; there is no requirement for a student to participate in the pledge of allegiance.
Chances are that the kid was (in some ways) waiting for a confrontation. Demanding that the kid stand and engaging him in an argument was nothing more giving him a little "soap box" to stand on. The teacher should have ignored him.
But this is what we Americans seem to like to do these days... that is: take something that is ultimately inconsequential and blow it up into a huge deal; giving voice to things that would otherwise be ignored.
