Lie detection: Part 2

I wrote recently about whether fMRI should be used for lie detection in court. US Magistrate Judge Tu Pham says "no". Science reports:
But while Judge Pham agreed that the technique had been subject to testing and peer review, it flunked on the other two points suggested by the Supreme Court to weigh cases like this one: the test of proven accuracy and general acceptance by scientists.
What I find interesting about this argument, as noted in my previous post, is that it's not clear that commonly-accepted "evidence" passes those tests: fingerprinting and eyewitness testimony are two good examples.
