Just to be clear, you're talking about prisons like Sednaya, the infamous "Human Slaughterhouse?" The one where Assad imprisoned thousands of political opponents, journalists, military deserters, Muslim minorities and civilians, and then systematically tortured and executed those people?
I do remember the same shit promoted when Gaddafi was toppled.
And then Western mass media stopped showing news from "freed" Libya. Because, you know, public executions and human slave markets kinda not something, their population should know about, unless it's done by "bad guys".
