You want to know the difference between today’s american cops and the russians and germans of decades past...? So do I. Last I checked they put their pants on one leg at a time every day. They all probably love their wives and children and waved to their neighbors when they left for work. You see, the important law here that has never been repealed is the law of human nature. You seem to believe it won’t apply to our boys in blue ( or black, that’s the color of the ski masks they wear on their late night raids). I’ll take the under on that wager.
But in the cross section of America, there are those in ALL walks of life who will refuse to be cowed, and who will stand up for what is right, not just what's convenient.
I hardly think your pessimism is worth celebrating, even if you're right. And in any case, resisting tyranny is not necessarily a means to an end as much as it is an end in itself.
