PROBLEM IS
-cops are trained to Shoot First...ask questions Later.
-most cops are scared shit-less. The MF's are afraid when they suit up---and happy when they make it back to the base. That's one of the reason's why they shoot first.

Some Lawyer will probably get to sue the **** out of that department. The City will pay this old man 500k. The tax payers will pay for this Cops mistake.

CLEARLY, the old guy was moving very slow. Any Rookie could have takin him out at any moment. He should have waited to see what the old guy was grabbing. He probably had a hearing problem and WITH THE LOUD traffic zooming by, didn't hear anything the Cop was saying.
