Thompson’s computer is confiscated for investigation following the attack. Police officer familiar with his postings:
He’s very angry. He’s ranting about America, more racially than anything else.
A picture is found on the computer of Thompson wearing a keffiyeh, and a disturbing conversation with a Facebook friend. Source:
He says American needs to be punished, from within, and he talks about Middle East issues. He says American is oppressing people overseas and that its military is too strong.
In other conversations his ideology sounds more race-based than derived from Islamism:
[He] seems more like a throwback to the anger of the 70s. He says that if there’s going to be change, American blacks need to make the changes. He talks more about revolution than jihad.
