It seems to me that, at one time in recent history, we were all told to let airplane hijackers have what they wanted, not to resist, and to let the authorities negotiate with them.
What did that get us?
Thugs only get away with it when you let them. Stand up to them every time, and yes, there will be some casualties, but in the long run, you will save lives.
This is what the people decided on the one flight where people rose up agains thte hijackers, and said they wouldn't go down peacfully.
It is part of civic duty to rough up baddies. It shoudln't be punished.
