This is the million dollar question and the fact they are stonewalling answering it tells me a lot.
I would say that all of them were killed by the police. For two, actually three reasons: 1. No video of the incident has been released and the police always video their operations, from multiple angles when possible.2. No transcripts of 911 or any police radio traffic has been released. 3. The arrest of every witness and probably some who did not witness anything. The amount of bail they knew or believed that the arestees could not meet. And last but not least, they are being held incommunicado.
Post of the day. Ain’t sunlight great.
