to be fair though, imagine this scenario
radical muslims who become americans are detonating bombs in america to kill and maim innocents to defend islam against the liars who claim that islam is violent and on a wild police chase (all of which has happened)
but lets up it a notch. they have body armor, they have rpgs, they upgraded their van to be armored against attacks. they take out the cops and continue on their path of destruction. no one can get close because they have rpgs to do this for days
a drone strike could take them out. or you could keep trying to stop them, and lose a few more dozen people
what do you do, mr president
