Laquan McDonald was the black 17-year-old who was shot 16 times by the police officer on Oct. 20, 2014. The video showing the shooting was only released by Chicago officials when they were ordered to do so by a judge in late November 2015.

But apology or not, the underlying substantive issue is that the summary execution of McDonald was the sort of atrocity that one would expect to see in what the U.S. once called "police states." In fact, one can imagine a death squad execution in El Salvador in the 1980s looking very similar on video to McDonald's slaying.

"Police state" is a term which has fallen into disuse since 9/11 with the adoption of so many similar practices by the so-called "democracies" in their domestic policies.
