We leveled entire cities in WWII. Do you disapprove?
There was no alternative, and sometimes you have to do things you don't approve of. In WWII we did not have the option to take out individuals to bring their machine to a halt. The entire cities were leveled in retaliation for the Nazi and Jap atrocities (V-2 bombing of London, rape of Nanking, Bataan Death March). Hiroshima and Nagasaki probably saved ten times the lives they took by precluding the need for an invasion.
In our case just a number of key individuals removed from each of the oppressive agencies would give pause to the rest, as the underlings would know that they are next.
