“Some officers were shot in the back,” said Brown, who added that this men were attacked “ambush-style” by snipers from an elevated position.
Or one might say, "Police-Style."
This is a bit unfair to those policemen who try to do their jobs responsibly everyday, and don't deserve to be killed. But sadly, our Republic has lost its way, and this time the only terrorists we can blame are ourselves. For the immediate genesis of our current headlong rush to becoming a full-on police state we need look no further than the disastrous supply side economics of the 1980s that still haunt us today, the G.W. Bush suspension of habeas corpus, the ironically-named "Patriot Act", privatization of things that ought not to be privatized -- schools, prisons -- and perhaps most important of all, continued neglect of reforms in our criminal, "Criminal Justice" system, with its extortion, seizing of property without due process, and its for profit prisons.
It should be no surprise that when you have a populace armed to the teeth with semi-automatic weapons, increasing numbers of desperate people in a country with a wide gulfs between a tiny number of wealthy, a shrinking middle class, and growing numbers of poor, and into that mix you throw government that serves as advocate for the wealthy and pays only lip service to the suffering of the people, you will have increasing instability. To expect something other is irrational. It is through these acts of defiance that change occurs when no civilized option, that has a chance of succeeding, is available.
I disagree with some of your points while agreeing with others.
I should point out that there were many more terrorist attacks on the police in the 1970s than during the past decade. The income inequality by many measures is much better today than in the 1970s. It is hard to blame "supply side" economics for this situation.
