From the New York Times:

The killing in 1967 of an unarmed demonstrator by a police officer in West Berlin set off a left-wing protest movement and put conservative West Germany on course to evolve into the progressive country it has become today.

Now a discovery in the archives of the East German secret police, known as the Stasi, has upended Germany’s perception of its postwar history. The killer, Karl-Heinz Kurras, though working for the West Berlin police, was at the time also acting as a Stasi spy for East Germany.

…

For the left, Mr. Kurras’s true allegiance strikes at the underpinnings of the 1968 protest movement in Germany. The killing provided the clear-cut rationale for the movement’s opposition to what its members saw as a violent, unjust state, when in fact the supposed fascist villain of leftist lore was himself a committed socialist.

It comes as absolutely no surprise to me that a socialist agent of the state acted in such a brutal, calculating manner; but does it come as a surprise to the left? Leftists already have much to answer for, but this event does much more than strike “at the underpinnings of the 1968 protest movements”. More than one leftist criminal organization rallied around this event to justify their actions.

Seriously, the irony here is delicious, predictable and heart breaking.
