I agree it wouldn't be helpful. It is similar to the problem of DNA evidence tests. The technique can be extremely certain, but the entire process chain must be evaluated in order to gauge trust. How likely is it that the evidence was correctly sampled, collected, was actually on the victim etc. For votes there is great benefit in having a paper process which can not be mass forged as easily as computer votes or tallies etc. It might take longer but it is of high importance.
