Oh, no. The case against this guy is airtight. He owned a handgun. And he was on the record as being pro-life and outspoken about the place of religion in civil life.

yeah...I got that part.

If the part about threatening co-workers is true - that is indeed very strange, but it only shows he was a man coming unglued.
Why was he coming unglued?
It could be he really was guilty - or the pressure of the investigation drove him batty.

I hope they will be able to get to the bottom of it, but so far it doesn’t look promising.
