Any evidence that she had any intent to hurt someone? Should the police also shoot drunk drivers and kids doing donuts in parking lots?
It appears to me that the officers involved are drilled every day to look for terrorist threats and it becomes an issue of every problem looking like a nail, when the only tool you've got is a hammer.
There is no excuse whatsoever for shooting this woman: she approached some barriers near the White House where she was confronted at very close range by the guards who tried to block her in. She panicked and rabbited off in her luxury car and was chased. Had she been armed, they would have known during that initial confrontation. She raced off through DC traffic and headed towards the congressional complex and then was riddled with gunfire with her baby in the car.
What kind of country have we turned into? Cops aren't suited, mentally or constitutionally for combat. That should be left to the professionals and used against foreign enemies, not mentally fragile moms in cars.
I guess it makes a difference where you live and work. It would never occur to me to second-guess someone who was risking his life to keep me safe. Hind-sight is 20-20.
