There are realities of modern America that never get any airtime. Not because of some spooky conspiracy to keep the prols uninformed, but just because said realities are so embarrassing no one with a salary wants to really talk about it.
This however was pure cowardice. The UC rent-a-cops already have a monopoly on physical force in this picture, but that's never enough for cowards. So they go out of their way to reduce their targets to terrified, incapacitated heaps. Otherwise, they might get mouthy or something when they're arrested.
And this, sheer cowardice even when holding absolute power, is exactly one of those ugly realities I mentioned at the start. I direct your attention to those eight years under Bush - most powerful empire in human history, and he chooses to go to war with emaciated wimp Iraq. Iran has definite connections with Hezbollah, North Korea has had nuclear weapons for nearly a decade, Iraq... couldn't fight back. And it's telling that when the insurgency broke out, the approval numbers went into a tailspin among the same crowd who cheered it on in the first place.
Americans are cowards, "conservative" Americans even more so. I could write a whole damn book about the many GOP wimp-outs from Reagen to Bush Jooner, not to mention the huffy Tea Party dweebs who bitch and moan if anyone points out the truth that they're a bunch of racist suckers. In fact, I think I will write a book! I'd title it Pussy Nation but that might be mistaken for something fun.
