From the video please describe what you think was the lack of consideration during the time that he was saying that he couldn't breathe.
The lack of consideration may have been born from ignorance of the officers with reference to his concurrent medical conditions which I tried to enumerate in my previous post. I don't expect them to have the clinical acumen of a physician, but they are not at all tune into the complaint that the man said he could not breath. That is dangerous in any setting.
I don't know if that answers your question. I hope it does.
