"Not necessarily"

He might have had to die. We don't really know. He probably didn't necessarily need to die, though.

City Manager Harry Black also spoke about the unreleased body camera video of the shooting.

"It's not a good situation," Black said. "It's a tragic situation, someone has died that did not necessarily need to die."

Also, if you've got a police force equipped with body cameras, and the body camera doesn't prevent the police from killing people, and the body camera video isn't  necessarily available to the public, well, maybe body cameras aren't necessarily there to protect the public in the first place.  What are they there for?
