Democracy NOW!'s coverage of the story:

The family members (specifically the son) have been allowed to hear the unreleased audio from the medical alert company, in which he says you can clearly hear him say, "Please leave me alone. I'm 68 with a heart condition, why are you doing this to me? Can you please leave me alone?" After which one of the officers calls him a racial slur and tells him to open the door.
The man's son is interviewed in the segment as well, in which he says there's audio of the medical alert company calling the police dispatch and asking to cancel the call because Mr. Chamberlain is okay, to which dispatch responds "we're not cancelling anything." Also, they advise the police to call his son, to which the police respond "we're not calling anyone, we don't need a mediator."
People can talk about how this is just a compounding if many misunderstandings, but even if that's the case, which I'm still not willing to concede at this point, at what point do we start holding our "peace officers" accountable when their misunderstandings result in the death of a citizen? And no, Paid leave (and even unpaid leave) are not sufficient punishments.
