Okay, here is one who has a few screws loose. She needs to be on a government watchlist if she isn't already. Clearly mentally disturbed.

Another deeply disturbed person. She should never be allowed to have a firearm or hire anyone to carry a firearm on her behave. There are too many lives at stake. We have to learn from our mistakes. When the warning signs are there, we need to take these people in custody.

Ok what is your address?

I'll happily report you as a disturbed person who should be professionally assessed for his own safety at the very least.
