If you have a condition like this and you are being told by a police officer who is pointing his Taser at you to put your hands behind your back, and then you don't, then it is you who have chosen to be subdued with a Taser. If you subsequently die, then it is your fault.
This guy could have signed the ticket, which serves as a bond to release him on the promise that he will appear in court to answer the charge. Once he refused to sign the bond, he was refusing to appear in court. Absent a bond, the police officer had no recourse but to arrest him. When he chose to act erratic and refused to obey the commands of the officer who was arresting him, then he chose to be Tasered. This was entirely the fault of the driver.
