I had to look that up.
Catecholamine - Wikipedia, the free encyclopedia
Sounds plausible to me. I know it
sounds implausible, but sometimes people being restrained just simply die from the stress.
I testified as an expert witness in a couple of court cases where this was the case. The person in restraint died, even though there was no compromised respiratory function, or compromised cardiac function. They just died. The doctors said it was something like "catecholamines", but I don't remember the exact terminology.
Basically, if a person is unaccustomed to it, being put in restraint is
tremendously stressful, both physically and psychologically. People just die from that stress sometimes. Sounds silly, but it's true.
In this New York case it sounds like the cops were doing the restraint very wrong, which is Not Surprising. Cops are freakin lazy. They hate training, and most view it as a stupid, time-wasting bureaucratic imposition (which a lot of it is).
