The Useful Idiot

The useful idiot or useful fool - made famous by a Vladimir Lenin is a person who thinks they are fighting for a cause without fully comprehending the consequences of their actions, and who does not realize they are being manipulated by the cause's leaders often used during the Cold War in the Western Bloc to describe the fools who did the dirty work for the party elites.

More modern example is the suicide bomber.

This is the best description of what is happening on the left today - "by encouraging people to interfere in law enforcement operations, the left is getting people killed.' All done to hide and initially interfere with the bigger issue - rampant fraud stealing billions from hard working taxpayers.
