Regarding witnesses: to be fair, I didn't believe in "John" from the Treyvon Martin case either, until he actually showed up at trial. So I was wrong about that, and I could very well be wrong about this.
But none of this really matters. I think Wilson is going to be indicted. I think he should be indicted, based on what we know. I think he likely committed a crime. I think there's is going to be a trial, and we're likely to be discussing it for months to come, just like Zimmerman. And in the end, I predict Wilson will be acquitted, because there's too much reasonable doubt, just like Zimmerman. And there will be justifiable anger, but no further rioting. Just like Zimmerman.
I also think that there will be repercussions for the terrible way the police have behaved here. Some people will resign or be fired. There will be lawsuits.
But the most important and saddest part of this whole affair is that it won't really change anything. Police departments all over this country will continue to stereotype black youths- not because the cops are evil, but because they honestly believe that it's the best way to fight crime. African-Americans will continue to feel victimized by the police, while refusing to acknowledge any responsibility for their problems. Liberals will continue to side with blacks in every situation, and blame the government, conservatives, the police, and themselves for the plight of so many African-Americans, but never the African-Americans themselves. Conservatives will continue to exonerate the police in every instance, blame blacks in every instance, and refuse to acknowledge that there is any racism at all, or that the American Dream doesn't always extend itself to certain minorities the same way that it does for white people.
And so we'll continue to have these sorts of incidents for decades to come. Rinse and repeat...
