American Red Cross was selling tainted Blood and factor 7
for 3 years during the Aids crisis. Until they came up with a
fast test, they just accepted contaminated blod.

The problem was that the French system was still doing it after the tests were available. The use of AIDS tainted blood was effectively done ‘knowingly’ vs ‘unknowingly’ because a test was not available. There is a big difference between the two. That is why the criminal prosecution. Look at the timescale.. three years vs over 10 years.
