(and that's pretty much all of them).
You can tell... because the story vanishes from the news after one day.
The woman who shot up the church in Houston had "free palestine" on her rifle. She is a Salvadoran immigrant who occasionally dresses as a man, who has been held in mental health custody on more than one occasion, and who divorced her husband because he was Jewish.
She covers pretty much all the left wing bases, doesn't she? Or he?
Any wonder you have heard nothing about her/him?
