Why wait to find out and confirm your rank speculation? You've been
perfectly happy to see people killed when the government doesn't even know
who they are.
"In Pakistan, Mr. Obama had approved not only “personality” strikes aimed
at named, high-value terrorists, but “signature” strikes that targeted
training camps and suspicious compounds in areas controlled by militants.
But some State Department officials have complained to the White House
that the criteria used by the C.I.A. for identifying a terrorist
“signature” were too lax. The joke was that when the C.I.A. sees “three
guys doing jumping jacks,” the agency thinks it is a terrorist training
camp, said one senior official. Men loading a truck with fertilizer could
be bombmakers — but they might also be farmers, skeptics argued.
..
Signature strikes in Pakistan were killing a large number of terrorist
suspects, even when C.I.A. analysts were not certain beforehand of their
presence.
..
Today, the Defense Department can target suspects in Yemen whose names
they do not know."
