A smart idea on their part would be to mix in some saline shots with the 'real' shots without saying so. That would decrease the side effect and death counts, and possibly "encourage" more to take it. I don't understand why they wouldn't/didn't give saline to Hank Aaron and Marvelous Marvin, especially since they were trying to get the black communities. Or any other high-profile celebrity (though I'm sure some have either gotten saline of dummy needles).
