There was no way the cops could have known that this man had an enlarged heart.
However, the man himself knew that he had an enlarged heart, and still CHOSE to take cocaine, CHOSE to take PCP, and CHOSE to attack a police officer and resist arrest.
One person who saw the video here at Oprano said he was still coming up trying to grab nightsticks, not putting his hands behind his head or sticking them straight up into the air... but still trying to attack.
And he CHOSE to do that.
The cops, however, had no choice but to defend themselves and each other.
Besides, I don't know too many beat cops who carry nets for 400 pound "10 feet tall and bulletproof" idiots in their trunk
