What is a "justified" killing? Police are not a jury, and they are not executioners. I understand self-defense, but often these claims are made when the other person was a perceived threat and not a demonstrated threat. And that to me is a gaping issue. Police are supposed to be trained in appropriate use of lethal force, and that should mean that they are answering lethal force with lethal force. Not meeting the potential for lethal force with lethal force -- that definition can apply to practically everyone if twisted enough.

And "we" do talk about diabetes, mostly in the form of universal healthcare and drug costs. Why can't people get proper healthcare? Why does insulin cost hundreds of dollars a month?
