I've wondered the same thing as Esther Goldberg writing for the American Specatator. Why is there no public outrage over the cold blooded murder of an unarmed woman in Washington DC last week?
[O]n October 3, Miriam crashed her car into a security barrier near the White House. She was surrounded by security men shouting at her and pointing high-power guns. Was it so irrational to try to escape, to protect her daughter from men pointing pistols at her? A chase ensued, and she then crashed her car into a median somewhere in the vicinity of the Congress. She was blocked by security forces from several agencies. She could not move. She was unarmed, and alone save for her daughter. In her car, unprotected. And then she was killed.
After the Boston Marathon killings, Boston police spent over 2 hours in a stand-off gun fight with the surviving bomber, Dzhokhar Tsarnaev. They threw flash-bang grenades to disorient him. They brought in a negotiator to talk him into giving himself up. Eventually he did, and he walked out alive. But Miriam was not given that chance. She was trapped in her car, just sitting there. And they killed her. They emptied multiple rounds of ammunition before dragging her body from the car, her one-year old child witnessing all this from the back seat.
