Cops retired cops all here say stun guns are very safe but what about what stun gun manufacturer say's ?

US Department of Justice study on electro-muscular disruption devises found that using stun guns might cause cardiac arrest in people with heart conditions. Every stun gun manufacturer posts guildelines that advise police not to use stun gusn on the young, the aged, women who are pregnant, or those who are disabled. At times police officers in the field disregard those guidelines and stun the very young or the very old—and, every now and then, with tragic consequences. Although they should not be, stun guns are sometimes used to stop people who ran and forced the police to chase them. They are sometimes used on people who did nothing more serious than curse at the police officer, spit at them or be verbally abusive. Stun guns are regularly used on people who refuse to put their hands behind them to be handcuffed; or people who are already handcuffed who refuse to get into the transport vehicle that will take them to jail. Stun guns, Amnesty International reported, are being used in situations that guns, batons, pepper spray would never be used. Stun guns—as deadly as they are—are being used as corporal punishment because kidney punching handcuffed suspects is no longer tolerated.
