Is there a telestrator in your living room that will cause you to go to jail if you mutter something negative about the government?
Much more sophisticated than jail.
So the actual message of the book was that living in England sucks, which as far as I can tell is still true.
On the other hand, if you start something like the Black Panthers, or MLK's planned march on DC, or the Ferguson protests, then something much more final than prison may be used to get rid of you.
I can be killed if I am a journalist and dare to say anything bad against my government.
So, not exactly the same, but not too different either.
