This is the price we have to pay to keep oppressing blacks, latinos, Muslims, and whomever the undesirable group of the month might happen to be. Your third mistake was underestimating the cowardice of Americans especially the cowardice and fear of white America towards blacks, Hispanics, and recently Muslims. Americans have given up most of their freedoms in exchange for a brutal, oppressive police force whose sole purpose is oppression, racism, and cruelty. What happened to you is totally fucked up, but if you think paying $100k in taxes makes you immune or somehow protected from this brutal oppression machine, you simply do not understand the forces at play here in America.
There you are wrong, starting with e.g. reporter Radley Blako and his readers, and extending to large swaths of the white or thereabouts population who buy books like Arrest-Proof Yourself (http://www.amazon.com/Arrest-Proof-Yourself-Dale-C-Carson/dp...) This was reified for me in ~2008 when a local cop played a game of chicken with his car and my body.
Some of it is that the author lives in Santa Clara County, California as mentioned in another comment. Citizens in Bay Area counties are allowed to own (some types of) guns, but by and large not to carry them, and that appears to help the Badge Gang feel they can treat nearly the entire populace as their playthings.
Take that too far in my part of the country, a combo of Greater Appalachia and the cultural South, and the calculus changes rather a lot. And in my county, when I last renewed my concealed carry permit, 5% of the age eligible population had one, and gun ownership is not quite ubiquitous, but extremely common and steadily increasing. And many of the cops are on our side; can you imagine a Santa Clara County law enforcement public affairs type confirming that a woman had an "absolute right" to use lethal force against some home invaders?
Radley Balko is one brave writer, that's for sure. But even he's just going to write about the atrocities here after the fact. Maybe what I should have written is not that no one cares, but that very few people do, and they cannot change anything. Even Balko does not realize the full extent of the problem of living in a police state like this, probably because he doesn't recognize it as a police state. And while his assessments of what exactly is wrong with our police in "Rise of the Warrior Cop: The Militarization of America's Police Forces", for example, are spot on, his solutions are lame. He understands the hate that communities in the US have for police, yet suggests that more foot patrols will help. We are way, way beyond that. Without strict liability laws and restrictions on police, there is no fixing this. While cops can get away with murder, there will be no fixing this. If having justice, which includes not murdering innocent people, is not enough of an issue for Americans to change this system of horrific, Holocaust-scale imprisonment, it really does seem like almost nobody cares.
For now, I think a good start toward this goal is to start seeing people--all people--as human. That's not just something the police have to do, but something I have to do vis a vis the police, and everyday people have to do vis a vis both police, convicts, and "criminals". I'm personally willing to let go of my hate for the police and the justice system in this country if and when we start treating all people like humans. That means we don't use the threat and actuality of rape, torture, and murder in jail as a punishment when the actual punishment is going to jail. To me, it means police and government officials are held not only accountable, but to a higher standard than normal citizens (worse penalties and certainly no immunity from liability). It also means not criminalizing everyday activities.
Until then, the only thing we can do is speak up, bring awareness, and hope the police don't target us. And probably one of the most important things, teaching our children the truth about police, not the fairy tale of "serve and protect."
