What of the $1.5 million the city was forced to pay to the sole survivor and families of two of the dead? You make this out like it came from the top, rather than just some idiot mayor. Mind you, yes, the information I have is from 5 seconds of searching, but this does not appear to be a federal "silencing dissidents" operation. Just a mayor fuckwit abusing his power in office to clear out what he considered to be a "disagreeable" civil rights group.
It's a matter of scale. Few groups shake the top, so the top doesn't care. Shaking the town, on the other hand, requires much less work. You can see examples of things "from the top" with COINTELPRO and the Civil Rights Movement or the plans to assassinate Occupy organizers if it endured as a large thing.
So... you want to enforce a policy that a majority of the population disagrees with because you're convinced that you are right and they are wrong and you are helping them? Do I have that right?
What fucking policy? What are we even talking about now?
And the wishes of the majority of the population have never directly mattered. The entirety of the political system is to ensure that their desires can be both known and ignored if necessary. The majority of Americans support severe electoral reforms, nobody runs on that. The majority of Americans wanted out of Iraq, took the better part of a decade (which is still way better than Vietnam). The majority of Americans oppose the drug war, still going. The majority of Americans think this is a Christian nation, countermanded by the Constitution. When Roe v. Wade was passed over 70% of Americans opposed abortion, 50% still do.
No, I don't believe in the fairy tale version of democracy. I believe in effective leadership with intelligibility from the general population. That's not too far off where we are, either, but it requires a certain amount of giving a shit. I'm not concerned about the government being able to push through whatever unpopular thing it needs, because it's always had that power. I'm concerned about whether or not they'll know what unpopular things need to be done for the collective good.
