Oh come on Gorilla - did you never experience the "request for volunteers" for "common cold" experiments. One assumes that if Porton had told the truth (just my supposition you understand), they could well have been very short of "volunteers".
How many people were experimented upon without ever being told what it was they were receiving? A rhetorical question of course since we shall never know but if high profile cases like this one and Gulf War Syndrome serves to stop such disgraceful tactics then it will have been worthwhile. There should be no time limit on these matters. I fully support drawing a line under what was done where it was anticipated no harm could come to any one and the truth was told.
