One good question I've seen repeated everywhere: with so much surveillance and with perpetrator posting so much "content" publicly in the last few days, how come security services didn't know this?
Did anyone report the content before these events happened? Or was it public to a degree that the people viewing it shared this person's beliefs?
This too is my question. Screenshot of the main guys post the morning before the attack included almost all the detail for it to be taken seriously and be acted upon before this nightmare.
Not that I personally supported those sites, but I understood /pol/ to be the far more level headed version of /b/... Guess I was wrong?
Or did reports of it to the police just fall on deaf ears given the source site?...
