I guess I was going too far by suggesting there was a deeper motive involved. Tyme, it looks like you were right that the bomb was clearly designed to simply do in the wearer.
Tyme, in regard to your statements about risking my life to save others. I work as a firefighter, so this comes as my job description. I have no problem taking SOME degree of risk to help or save others. But I am not going to throw my life away in an effort that I am untrained for, or something that is hopeless. There is a big difference between risking your life and throwing your life away. A non-life threatening example might be me offering my time to help you fix your transmission when neither one of us has any idea what we are doing and have no instructions to go by. I may have the best of intentions. My heart is in the right place. But I would be willing to bet that at best we won't accomplish anything, and at worse cause you more problems and more expense than you had to begin with. It isn't a question of my not wanting to help people, it is a question of whether I am capable of helping them or am I just agrevating the problem. Over the last 20 years I have worked as a paramedic. I have had more than one occasion where I simply wasn't sure what to do. My findings were not conclusive. My plan of treatment was not clear. The signs and symptoms of the patient were vague or unusual. Instead of just doing SOMETHING and risk it being the wrong thing, I simply did what I know would help the patient and quickly got the patient to an emergency room where they had more diagnostic equipment and more education to diagnose the problem and treat it correctly. I distinctly remember a call many years ago where I thought I knew what was going on with the patient but I wasn't sure. Something didn't seem right. I called the hospital on the radio and talked to a doctor and he agreed that I should give drug "Z". I had a gut feeling that I shouldn't do that. I didn't know why, but my gut told me not to. So, I didn't. When we got to the hospital, it turned out that what I thought was wrong with the patient was incorrect, and the treatment that I was considering and that the doctor ordered would have almost certainly killed the patient. I did only the very minimum to help this patient, but by doing nothing more, I possibly saved this persons life. When dealing with people's lives, I early on realized that if I wasn't 100% sure, I would only what I was SURE would benefit the person involved. This type of call is very infrequent. In 20 years and tens of thousands of calls I might have had a half dozen or so.
Sometimes not doing something is the better course of action than taking a wild shot in the dark.
Speaking of shots in the dark: as was mentioned, it doesn't look like taking the handcuffs off the prisioner and giving him a knife would have accomplished anything. The cops that were THERE on the scene very well might have had a better idea of what was going on than we did. We were quick to jump all over the cops from the comfort of our computer. I am just as guilty of this as anyone ever has been. But, it has been proven to me over and over that a lot of the time, I don't have enough information to form a sensible conclusion.
