I'm gonna play devil's advocate for a moment...
Perhaps he believed what many people believe, that a defibrillator restarts the heart. Even the article regarding the incident stated that
Defibrillators are used to restore heartbeats, but they can also stop a heart.
That of course is not what occurs in defibrillation which stops the heart and its dysrythmia in the hopes that the heart will restart itself in sinus.
Martin, though an EMT, was not yet qualified to use the defibrillator and had been told it is not something to play with, Bush said.
He was told not to "play with it" but was he told that it could be deadly? Yes, it is common sense, but when giving people access to potentially deadly equipment, we should never ASSume that said people have common sense.
I believe that justice was served with his conviction, but I also agree with the previous poster that the system has a lot of ills that need to be addressed.
I am so sad for both families involved, but especially the young woman's family. What a sad and avoidable tragedy.
