Take out jihadist who is actively trying to attack or contribute to attack on United States, sure. But if they are an American citizen, they should first be prosecuted, given due process, and taken care of like all other US citizens. It might sound crazy to some, but it would be Unconstitutional to do otherwise. The government should NEVER be allowed to cherry pick when they want to follow the Constitution and when they don't want to follow it (I know I know, they already do this). This is the purpose of the Constitution, to restrain the government from becoming tyrantical. If you start making exceptions to the rule of law, our republic is lost.
