Now as I recall it came from ARKANSAS prisons when one William Jefferson Blythe Clinton (aka; Willard, Billy Jeff, the Bent One, the Sink Emperor, etc.) was governor. I also seem to recall that he signed something (like a gov's EO) that prohibited the testing of said blood of HIV, AIDS, Hepatitis, and other little nasty killer blood contaminants!
Along with the people who got the bright idea to sell prison blood internationally after the US had condemned it for domestic use,
And the nice people at Connaught Laboratories who did not know, and made no effort to find out, that the ADC on the bags meand Arkansas Department of Corrections before they used the blood to make Factor 8.
And the Red Cross for putting its budget concerns ahead of the cost of adopting known techniques for screening and treating the blood.
The list is endless.
