I agree with you that there isn't one correct approach in these situations. I can't agree that there was any possibility of authorities having made a good faith effort in the situation though. The government lost any shred of credibility and moral high ground when they brought M1 Abrams tanks into the situation. The children are in danger so we'll point a high powered tank cannon at the house? How will tanks save the children? Not to mention breaking the longstanding policy of not using military weapons against US citizens. That situation was an authoritarian massacre similar in style to Tiananmen Square.
