"Mentally unstable" is not an accepted medical diagnosis, it's a huge gray area.

Even words like "psychosis" don't mean anything. EVERYONE has a little psychosis in them. Look it up.

I don't want the government putting people on a special list because of bullshit "diagnoses" like that. The whole "sex offender" thing is bad enough.

Sorry, that's what I was saying; that this is already the case. It also doesn't work if said nut-job doesn't say to his doctor, "I can't make next week's appointment, because I've got plans to run through a shopping mall with a katana. Can we reschedule?"

Have you been talking to my boss?

I said it like Lucy Lu on Kill Bill....Katananananannanananananannanana

You'll have to be specific. I talk to lots of people. Unfortunately some of them can't be seen by others.
