If the evidence is weak, contradictory, and problematical, Oswald did it. (sarcasm)
The evidence against the former sharpshooting Marine and self-described Marxist, Lee Harvey Oswald, may seem contradictory and problematical at times, Iacoletti, but how is it weak?
In lieu of a more rational "theory," i.e., one that doesn't require the witting participation of lots of evil, evil bad guys and really, really bad gals, yeah, Oswald did it.
What rational theory have you come up with so far, Iacoletti?
