Interesting story what was the end result?
I don't believe he made a mistake merely had an observant person notice him.
The problem is dueling uses. A car can be used for escape or pursuit.
I am surprised the women weren't arrested for harassing the poor Arab in SF.
I've got an email out to a friend at BART to see what became of this, and to verify the story. When/if I know, you'll know.
