I wouldn't be too sure of that. lain:
Perhaps you're right. But I'm sure there could have been better tactics.
For example, how did the surviving brother manage to escape in a car after a gun fight? Why wasn't the road blocked or covered with stingers to prevent escape? With blocked escapes the police could have stayed safe, avoided a guns blazing scene, and taken time to resolve the standoff with less risk to everyone involved, and less chance of escape.
I might be really wrong in these ideas, but then the experts can think of better ways in which the situation could have been dealt with without giving the terrorists the wholesale disruption to life that they wanted. Do the police usually close down cities when there are murderers on the loose?
