I agree this is a tragedy. But I do think it should be reported entirely without the use of the word TERROR. Disaffected youth, extremist political views, surveillance, suspicion, violent altercation. Where's the TERROR?

Be alert, people - there are political agendas at play that want you to be scared. They are going to do everything in their power to attach loaded words like TERROR and TERRORIST and THREAT to events and circumstances that have, in other times, been handled more discretely. Yes there are crazies out there, but there's a difference between responding appropriately, and fear-mongering
