I say we be patient, find out who did it and if they are overseas, start up the drones. Send them in formation and blow their asses to smithereens even if they are living in the same apartment with generations from nine to ninety nine. if they are here, make sure they do not see the light of day from capture to death.
This is the problem. Your suggestion will create a cycle that never ends.
Sit down and take it is for the birds. What should we do otherwise?
