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.
first rule of actually commiting (useful, impactful) violence…don’t tell anyone online or otherwise not down for carrying it out that your going to do it.
you live in a police state where practically everything online is being watched and catalouged 24/7, act like it.
the bar for violence is incredibly low, long as you just…stfu and don’t straight up tell people your going to do X, you can probably get away with it with a little bit of planning and common sense
