There is a very simple reason there is no "smoking gun", or any other kind of evidence. Put away your paranoid suspicions abut what I "really think" and the reason for the lack of evidence ought to be crystal clear.
You are the one saying there is no evidence. I am saying there is no smoking gun evidence. It's not paranoia when you sound very much in your questions, posts and positions exactly like those I have heard and seen who are exactly what you claim not to be. Above you posed this question: "If the races of perpetrators and victims were reversed, do you think this might have made the national news?"
Fact is everyday crime is not national news, but it is news when a grown man shoots an unarmed teenager and it takes a national outcry for something to be done about it legally. And I am not even saying Zimmerman is guilty, only that he should have been arrested for it. If in the examples you raised, the perpetrators were prosecuted, you have your answer as to why it wasn't national news. But I think you knew this which is why you ignored my first post and why you ignored my post to you about "profiling" in another thread and would rather focus on these sorts of posts. Why do police term Black men as "#1 males" when black men make up, what 12% of the country's males? Because that is the profile they have created for criminals which is in and of itself inherently racist.
Statistics show that crime is not a race issue at all, but rather a socio-economic issue. It just so happens that minorities disproportionately represent the poorest segments of our society. But I am sure Jim Crow had nothing to do with that at all.
Diving what you think based on what you say is actually a reasonable response, and not paranoia. And it is crystal clear. It's no longer fashionable to be a racist in America, so racists actually have to hide behind other issues in stating their racist agenda. This may or may not apply to you....I don't know.
