Wrong answer. It's not a function of law enforcement to allow people under arrest to "wait as long as it takes" (i.e., as long as they want) to be apprehended. Had they " waited as long as it takes," law enforcement would still be waiting for them to come out. 51 days was more than generous; and provided ample opportunity for the Davidians to vacate the compound peacefully. They chose to remain there indefinitely in defiance of the law and then to take their own lives, including the lives of their own children, when the law moved in to drive them out.
There is far more at issue here than the role of "law enforcement," which seems to hold a special place in your value system.
This was not an ordinary situation. The safety of 21 helpless children, some just tots, was at issue. If you do not regard that as having primary importance the most I can say is it's your problem. I don't have to live with you. You do.
I do have the impression you are a member of law enforcement at some level, which adds to the explanation of why that job category leads in examples of suicide, alcoholism, and divorce. But, whatever the reason, there is no point in laboring an issue which you obviously (and sadly) lack the capacity to comprehend.
Some day you might come to realize why that's a serious problem.
