Faster than light neutrinos?

They can be shown going backward in time on a feynmann diagram and quantum states of particle and anti-particle are interchangeable under cpt reversal - but they do not undecay and they do not travel backwards in time in a lumpen reality sort of way. 

AS an example - the positron in a PET scan can be perfectly calculated in qed etc by thinking of them as an electron travelling backwards in time - but to make a picture of the inside of your head they are a positron going forward in time
