Where does it say “violation of this dress code punishable by PRISON?”
He didn't violate the dress code, since a picture of a gun is obviously not "violence." His offenses were more along the lines of politically incorrect thoughtcrime.

Of course, the kid was caught with a “secondary” violation because he refused to do something an officer instructed him to do. The whole thing is an exercise in poor judgement by the officials involved. If a student is deemed to have violated the school dress code and refuses to comply, the best way to handle it is to simply tell him/her that he must comply with the “rules” or be suspended from participation in school until he decides to comply. Same with refusal to comply with any other standard set by the school (which should have input by parents before adoption, but that’s another matter).
Then, the student (or his parents, or both) can appeal the suspension and get a hearing on the matter. There was absolutely no need to involve an “officer” and allow it to escalate this far.
