Very myopic view Pearl. When someone is running at you with a deadly weapon, you don't zig left while they zag right. And the police do not ask for, require or expect 100% safety. They know they put them selves at risk and do so willingly so you and I can sleep easy at night. But they want to go home to their families and are not willing to throw their lives away so some idiot wanting to kill them succeed. 

I would like to see more scrutiny on deadly encounters but honestly believe that APD and AST are top notch police officers who risk their lives for us daily. Suggesting that they not be allowed to protect themselves, or that they should endure a higher level of danger is completely unacceptable.
