The comments here seem about evenly divided between "someone should have shot her" and a collection of  humorous quips.

Clearly Ms. Fay's actions were irrational and dangerous.  Indeed, it's fortunate no one was killed or injured.  It should be equally clear that she likely acted during a psychotic episode.  This doesn't "excuse" her actions, but I think it does explain them.  

Mentally ill persons act irrationally..Yes, that's a "well, duh" statement, but it seems people often forget irrational behavior is a "sign" of mental illness.  

Ms Fay's actions were, from all I read, a manifestation of her mental illness and I hope she receives the mental health treatment and care she needs. 

 Not to be too much of a prig, but, IMO,  there's absolutely nothing funny about this incident.
