Personally, I happen to agree with you whole-heartedly about the relevance, substance, and accuracy of the Biblical writings. But again, that boils down to a matter of faith, which is stronger, and more dangerous, than any established government. As for the Constitution, those issues which it does not directly establish precedent, are interpreted by the Supreme Court. Is it out-dated? Probably. I'm of the mind that it is all pretty nifty in theory, but the practical application proves itself to be much more difficult. That is, unfortunately, a problem with any system designed to govern an animal as unpredictable as man.
The LA riots? Were created by those living in sub-standard conditions (for a plethora of reasons, none of which were "whitey keepin' us down"), who were reacting to a perceived slight. That perception was fueled by their living condidtions, but the unfortunate fact is that Rodney King was a f*****g moron, strung out on crack, travelling in excess of 100mph in a Hyundai, that was not bright enough to lay down when 5 guys with guns, clubs, and badges told him to. What did he expect them to do? Tickle him? The whole mess was a byproduct of stupidity, not race...the race card was an excuse.
As for Katrina, it was a disaster. I'm not a Bush fan, but it wasn't his job, that's what FEMA is for. Of couse when the majority of the effected population is black, the race card comes out again. I could expound upon the quirky by-product of the 1960's called reverse-discrimination, but that's another topic for another time.
