I used to flaunt my computer skills back in school, because I knew if/when something got hacked I could explain exactly how it was done, and remind them that I'd warned them it could happen months earlier. (This exact thing did end up happening.) The authorities at my school seemed less prone to complete lapses of logic (as demonstrated by the police in this article) so I wasn't so afraid of being unable to defend myself in the face of unjust accusations. (Logic and reason sufficed, thankfully.)
