Mom: Okay, obviously I am anti-police brutality. But that doesn't mean I have to be anti-the-police. Look, 25% of these suspects are unarmed, which is horrible. But that means that 75% of them were armed. The police have to deal with that every day.
Son: I guess what you're saying makes sense, but isn't that their job, Mom? I mean, if you killed one out of every four of your patients, wouldn't that make you a pretty bad doctor?
Killing 25% of your patients would definitely be a negative. But in order for this analogy to work, you need a huge majority of that 25% of patients to be actively trying to kill their doctor. Or other people around them. Something that most people in hospital waiting rooms seem disinclined to do.
Maybe if more hospital patients attacked their doctors and tried to kill them with their own scalpels, like Michael Brown attacked Darren Wilson, attempting to kill Wilson with his own gun, you could pull that off. But in reality, it’s just not a very smart thing to say.
