Not quite always.
A certain young friend of mine accidentally took a pocket knife to school about a year ago (which another child saw briefly), and then lied about it (vehemently), and then was caught in said lie.
We had to spend some time chatting with the Principal and others. It had the potential to get very ugly. I’m happy to say that the school administration were cool-headed and reasonable.
Said child won’t make that mistake again.
