Morning mate, What I am driving at here is that it is not 75% of people convicted by eyewitness testimony but 75% of those found to be wrongly convicted.....Yes I am using a total count but only when directly related...let me try another way...

Sorry, but I think we are still saying the same thing in some respect, my initial post said:

Eyewitness testimony is directly responsible for 75% of Wrongful convictions overturned by DNA.
Isn't the bolded the same as your qualifier? of all wrongful convictions, that have been proven incorrect by way of DNA evidence, 75% of those examples are incorrect.
That is 75% of everything we have
had the opportunity to definitively prove, and not have to rely on a witness any longer.
Which still strikes me as an alarming statistic.
This part I am good with until....:

10000 convicted
5000 of these are through eyewitness testimony alone
out of the 10000 convicted 10 are found to be innocent through modern techniques.
out of these 10 we know 7.5 are those that were convicted on eyewitness testimony.
This would mean that eye witness testimony would carry a rate of
7.5/10000 on total convictions
or
7.5/5000 on eyewitness testimony convictions...
Here, I agree with this, as this widens the scope, however of you change that 10 to 100, everything goes up by a factor of ten. So I could change that statistic and make it look the other way based on a whim. What it is, is in cases where we have
an opportunity to get a hold of DNA evidence, which is a factor being discarded that I think could affect the above statistic dramatically, but I also have no idea how one would firm that figure up, but as time goes on I expect this will become more care will be taken, and DNA will be considered more important.

so out of total convictions it translates to 0.00075
or
Considering the large numbers you have used to illustrate the point, is that percentage still not translating into an alarming figure that is unacceptable? I maintain that
one is too many when the judgment is based on another person, who can be affected by too many interferences. If ten in one hundred thousand are wrongfully convicted, is that acceptable? And considering CNN cited a figure of 7.3 million in the system as of 2007, that is a significant number of innocent people who at worst could be facing death on someone's say so. People fight fluoridation on less convincing statistics and it is
beneficial to people.

that eyewitness testimony had a failure rate of just 0.0015% on convictions based on eyewitness testimony alone
so the rest of the numbers are crucial in determing what exactly that 75% represents..
But I do not think it is. That is a figure based upon what we have had the resources to accomplish, and within a system that still employs the method without verification. What would that figure look like of all eyewitness testimony could be reconsidered with DNA evidence? I would suggest it will rise dramatically based upon the samples we have to work with, and the statistics those sample produce. I think what is missing here is proportionating the number of total conviction against that which we have had the opportunity to sample.
I do not think the significance of the 75%
sample can, or deserves to be overlooked, or washed out. It is still innocent people who are paying for someone else's mistake because someone did not actually see what they claimed to see.
