Wow. It technically is. The thought police are here. Oh balzzz, everything I'm typing on here...I can't stop myself, the thoughts just keep coming and they end up on the screen. What can I...oh, just stop typing. Duh. 

It's not like he held a gun to his temple. Show me a single threat on the internet that is not empty as fuck. Poeple say lots of things on the internet.

The magic word is context and nuance. Law isn't black and white.

That's why downloading an illegal MP3 isn't the same as conducting an armed robbery of a record store.

Sorry, but intent is a very big differentiator in law. I'm saying there is nuance in law that is very important. There are certain degrees of crime and posting a picture with some empty words on Facebook is not the same as  threatening someone personally with a gun and putting them into immediate danger. If we'd instantly incarcerate everyone for posting stupid stuff on Facebook there'd be no more more people to log into Facebook to see those things.

I'd say taking away his weapons and banning him from posting onto social media for a few months would be a good learning experience for this guy. Going straight to jail for a very minor offense only makes things worse. Getting put into jail by a snitch is a far greater motivator for real violence than any Star Wars spoiler could be.
