currently the USA is a democratic nation with its own constitution and laws.

The Executive branch (Obama and feds ) implement the laws.

whatever the history might be the biggest reason behind the CIR is "political calculation" more than compassion or anything else. here why going back in history might not make much sense ( especially beyond a century ) to make decisions about current laws:

Human migration have taken place as long as mankind existed, in fact if you understand terms like "bottleneck in human evolution" ( all humans currently living on this planet are very close knit relatives as compared to many other species ) etc. and something about anthropology etc. I can go on but I dont want to bore anyone and I am not interested trying to make any further points.

really not sure what your message was here. I tried scrolling up to previous posts to get some context but still am not clear on your point. What has anthrologic evolution of man got to do with todays laws?

I'm not trying to be a jerk..really trying to understand it coz I'm a geek when it comes to anthropology, archeology and history.

viz - just responding to anthropology piece. I think what I understood from indiani is that "We all (humans) are quite related to each other (by way of what genome project established)". However there is "bottleneck" in evolution where between humans and other species there is not a whole lot of species that we can point out to to show a clear pattern of evolution going from point A to B to C (where C is humans. B is some intermediate step and A is the Amino acids!!! A to B is well documented and understood. But B to C is either not understood or the leap is just too much to fathom - how it exactly happened).

I too will wait to hear from Indiani to if my understanding is correct.

p.s. - One of my coworkers was originally from Alabama. He was kind of ashamed of his southern roots and would many times say this to me that humans left Africa barely 50-100K years back. (implying that all these differences we see today - Japanese vs Africans vs Asians vs Whites - are really quite superficial.)

genetically all humans across all races are so close compared to other species for example chimpanzees. ( chimapazees look the same but they are whole lot different from each other in reality compared to us ).

The theory behind this phenomenon was
1. at some stage in human evolution, apart from small community in africa rest of human have perished and that small group of africans have grown in size migrated everywhere ( bottleneck theory )
2. everyone in the world have a common graetgreat...grandmother ("mitochondral eve" ).. read in wikipedia , quite interesting and scientific ( not some woodoo..)
3. everyone of us ( 7 billion of us ) again have a common father ( Y-chromosomal adam )..again read in wikipedia..

these are scientifically quite accepted and the facinating field of genetics have made this possible.

Bottomline: we are all very close relatives ( atleast for some of us who believe in science )

sorry off-topic but some have asked and since some may have young kids who might develop much better world view even if its not much practical significance to most of you.

P.S: please don't get confused with biblical adam and eve
