For everyone talking about him having a weapon at school, I present to you Florida State Law Section 790.001.
(http://www.myfloridahouse.gov/filestores/web/statutes/fs07/CH0790/Section_0790.001.HTM)
?'Weapon' means any dirk, knife, metallic knuckles, slungshot, billie, tear gas gun, chemical weapon or device, or other deadly weapon except a firearm or a common pocketknife, plastic knife, or blunt-bladed table knife."
The definition for concealed weapon is different however.
?'Concealed weapon' means any dirk, metallic knuckles, slungshot, billie, tear gas gun, chemical weapon or device, or other deadly weapon carried on or about a person in such a manner as to conceal the weapon from the ordinary sight of another person."
After watching a lot of the "RIP Dylan Nuno" videos on YouTube, I get the feeling that this wasn't a case of "poor, misunderstood kid turns to bullying to raise his self esteem but he really just needs a good friend". Most of the videos show him hanging out with a lot of people and while I can't get into his mind to know EXACTLY what he was feeling, it definitely seems like he was just bullying to impress people.
Also, unrelated to what I said above, but this comment on one of those videos made me laugh:
"IF YOU HAVIN BULLY PROBLEMS I FEEL BAD FOR YOU SON, I SPARED 99 LIVES BUT MY KNIFE TOOK ONE"
