jales said:yea and like Fizhik said. Even with all the n eye for an eye..
you'd have to be 100% sure.. and you can't ever be 100% sure or anything.
In addition, a DNA laboratory is made up of humans, and humans make mistakes. A tube misplaced somewhere. Or a few thousand bucks given to a certain person - "hey we really need to make a conviction... I hope the DNA analysis results will match. Wink."Cosmic Kid said:DNA is not 100%. It is only 1 in the 100's of millions, billions, or even in the trillions. That is guilt beyond a reasonable doubt.

Where did you get your information? Below is where I found mine. If collected properly - DNA is the number one factor in determining guilt or innocence. I agree with you about reasonable doubt..however..that's based entirely upon the law and interpretation. Scientific methods today are highly sophisticated..and coupled with intrinsic data. (Which most of us never hear about unless we're involved ourselves..as in the jury). I would have to disagree that such results could stretch into the millions, billions or trillions. Sorry.

And I would just like to add..a question. What is the percent of people in prison claiming to be innocent? I'd venture to say almost 100% Funny..some claim science is flawed..but insist human nature should not be judged within scientific measures.
mimizu said:You didn't convince me.. #_# I still don't think that criminals should be stoned or anything cruel like that. If they must be executed, then it should be a "humane" execution. An injection or such.
Your comment about 100% of people in prison claiming to be innocent is cynical. Sure, a criminal will claim that they are innocent. But there are still innocent people there. And I don't want an innocent person to be stoned. Even if the chance is 1 in a trillion, I still don't want them to be stoned.

Ok Counsler, you're fast on a keyboard, Ill give you that. I'm having problems keeping up. I'm not a DNA Profiler. This is not my area of expertise. LOL (though, at this point, I stand by everything I've typed as true).
Here is what I've gathered, through my many minutes of study on the subject:
DNA is unique from one individual to another. I agree, as I have alluded to in a previous post, that it is the number 1 scientific way of identifying any given individual in a crime. (From what I've heard, fingerprints are becoming yesterday's news).
However, it's the INTERPRETATION of the DNA samples wherein lies the rub.
DNA is different for everyone, yes. BUT...do not forget, everyone also has DNA. How to differentiate one persons DNA from another persons DNA is where the science begins to meet it's limitations. It still is yet to be...that you can take one DNA and say with 100% certainty, that they are both from the same person (is my understanding, so far, anyway).
It has something to do w/ markers (loci is the name of one marker, there's lost of 'em..46 loci?, and other markers too, unless im mistaken). Anyway, all of the markers for a given DNA sample are not matched. I(only 10, 14, whatever).Therefore, there is room for error, because you are excluding a person's DNA from what could possibly be other sets of DNA. Here is the text I've been reading, it's too complicated for me to be able to understand. Anyway...
I'm thinking (however, I'm not certain, YET) that if a DNA sample is taken from a crime scene, and you give a sample of hair to see if it matches...then yes, it can be determined w/ 100% CERTAINTY if one of the markers is NOT A MATCH. (that's why guys are getting outta jail, they KNOW their DNA CANNOT match, w/ 100% certainty..ie, some markers do not match).
But, seeing how all of the (46?) markers are not tested (yet), when their is a "match", it's only matching the markers that are/were tested. it's still not 100% CERTAIN that it couldn't yet be wrong (if, say, all markers were tested). That's why DNA match is quoted in percentile, instead of saying, "it is a 100% match". But, I'm gonna find out from a person who talks english
Arianna, btw, your link also refers to DNA as "exclusionary evidence" iirc. ie, it's excluding everyone else, it's not saying it is you, thus, %'s. Thus, if you are saying that DNA is an EXACT, 100% ERROR FREE identification system, then, at this point, I believe, you'd be wrong. (of course, it is 'good enough' obviously, because the odds of it NOT being you are so unreasonably high). Anyway..

It's complicated, but I believe I can get a layman's explanation from a friend...
