The other problem overlooked in this analogy is that the killings are the most extreme symptom of a tyrannical police force that terrorizes (black) American citizens at an incredibly high rate, from harassment to physical abuse. Protests against the police are using killings as an example of the problem, not the complete summary. And, to be clear, the police treat white Americans very poorly as well. It's just that they somehow manage to treat black Americans even worse.
