Who are we to pass judgment based on a short article? I admit that my first thought, too, was that they should simply wait her out, but it is not for me to judge without knowing all of the facts--that is why cases need to be handled by the judicial system. The police may have known something that we do not. They may have had reason to fear that she was a direct risk to her children or to other bystanders. They may have intended to wait longer but then fired first because, seeing that her shotgun was aimed at them, they perceived her finger moving to fire. She set up the negotiations to fail. She did not merely verbally threaten, but physically, visibly threatened them. The police made a hard decision. If it was wrong, at least I am not competent to say with such limited information. But at the very least, I am thankful that I myself did not have to make that decision, because I cannot be certain that in split-second timing I would have made the right one. It's easy for me to talk now about what should have been. It would not be so easy if someone were actively pointing a shotgun at me.
