So if I put on a nazi blog that said something akin to um I’m going to kill all of you… Given I don’t know who they are beside username and where they are at would I be arrested? How is that different from what the 20 year old did? He was just more specific as far as I can tell.
Depends quite a lot on the orifice.
If you let it out through the mouth, all the laws apply. No excuse. Especially stupidity is no excuse.
If you let it out of the other end: less harm.
