require the manufacturer to include 2 cameras and 4 darts.
The manufacturer's warning is noted by Amnesty International:
There are continuing reports of police officers using multiple or prolonged shocks, despite warnings that such usage may increase the risk of adverse effects on the heart or respiratory system.
Deaths in the past year include Allen Kephart, 43, who died in May after he was stopped by police for an alleged traffic violation in San Bernardino County, Ca. He died after three officers shocked him up to 16 times. The officers were later cleared of wrongdoing.
Last November, Roger Anthony fell off his bicycle and died after a police officer in North Carolina shot him with a stun gun. The officer reportedly shocked Anthony who had a disability and hearing problems because he did not respond to an order to pull over.

The second camera and additional 2 darts could be used to discourage police officers from disregarding the manufacturer's warning. If a police officer unnecessarily used multiple or prolonged shocks, the second camera could record him being Tased with the second pair of electrified darts.
