How do you know they didn't take the matters seriously?
What's to say that they weren't 'fooled' by his improvements after therapy?
Very true, and people with mental health issues, or, who are just plane old evil, get pretty good at looking normal, when they need to. I always go back to Ted Bundy. Looking at the outside, folks had no idea, what was going on, on the inside. There will be "flags" that folks close to him, will take note of, and see, in hindsight, with this guy, but hindsight is always 20/20.
I've not had a lot of time to keep up with this one today, but it seems that it was tit for tat this time. TX was a RWE, and OH, a LWE. Extremism, in anything, (politics, religion, animal rights, etc...), should not be taken lightly. Most extremists are harmless, disgruntled, keyboard warriors, with an "agenda" to promote, or feel they're saving the world from the "evil" out there, but any threats of violence should be taken very seriously.
