I posted this because it's such a perfect metaphor for the shrinking-violet left's response to 9/11.
Run and hide, fear of using overwhelming force, feel really bad for the victims, rely on police (the U.N.) to handle the matter. Of course, they could all have well been dead by the time police got there.
Surely somebody on that train had something in hand that could have been used to clobber the psycho. A briefcase, a laptop. A kick to the groin. Wimpx.
