The Taser does not raise heart rate levels, but the excitment of the fight does. Add in cocaine or a number of other drugs, plus a life of drug abuse, yup, people are going to die.
The key point here being that, if the Taser was unavailable, the stimulus of the ensuing physical battle would be more than enough to elevate the heart rate and cause the death. Again, think of the ticking time bomb of the fat man with the heart condition on PCP.
Interestingly enough, once he died, what was the first thing everyone in Cincy was saying?
That the police were at fault
becuase they just wrestled with him
when they should have had a Taser so they could have used that on him.
No, I am not making this up.
The moral of the story is that when you are the police, if someone dies it is your fault, regardless of whether you:
Did too much
Didn't do enough
Used a taser
Didn't use a Taser
Addressed the threat
Didn't address the threat
Escalated
De-Escalated
Used enough officers
Didn't use enough officers
etc etc etc

PS This is not to saythat in-custody deaths are never the police's fault. I can think of two cases off the top of my head that clearly were...but neither of them involved the Dreaded Electrocution Device of Death.
