I think that's uncalled for. The soviet constitution would never tolerate free speech or due process.
That's not entirely true.
Let's take a look at the Reagan years, just before the Soviets began their decline.
It was completely lawful in the USA to stand in front of the White House in Washington, D.C., get up on a soap box, and shout that you hated Reagan and everything he stood for.
At the same time, it was completely lawful in the USSR to stand up in front of the Kremlin in Moscow, get up on a soap box, and shout that you hated Reagan and everything he stood for.
See - same freedom of speech, to say the same things.
