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.
I recommend looking into how much warning ACTUAL mass shooters usually give.
I totally believe your friend didn’t mean anything by it, but assuming the cops would just feel the same way without knowing anything else about him is delusional.
Please do not call him my friend. Do not hang out or have never been that pissed at something to take someone elses life. He was just near us. But thank you for the engagement
