As far as I can recall, people were not required to go through the metal detectors at these airports: MIA, FLL, BNA, EWR, PIT. MIA (at least last time I was there in December) has some lines that do solely metal detectors and some that do solely scanners. That is, until the scanner lines start to get long and they start putting everyone through the metal detectors.
I've always opted out (except once at EWR when I was with a large group and the screener took longer than the 5 minutes I was willing to wait) and about half the time I've gone through the metal detectors. In fact, last week at PIT, I tried going through the metal detector on my way to the pat down area and was told to go around it.
