LP--
I guess we are talking past each other.
1. For me, there is a fortuitous circumstance: The JFK motorcade passing right by the TSBD, in fact making a hairpin turn in front of the building. The exact route disclosed in advance by three days (Nov. 19, newspapers). The stockade fence-GK provided the venue for a diversionary smoke-and-bang show. That's a pretty good assassination format to chance upon by luck. In fact, it worked.
2. Upper floors of the TSBD often unoccupied. LHO had legitimate entry, could secret in weapon(s). Even hide the weapons in boxes. Again, a near-perfect set-up.
3. A known Marxist sympathizer, LHO, who had met with KGB and G2 in MC, and made extreme statements regarding JFK. A Marxist seeking passage to Cuba. I suspect LHO was in some ways a mentally ill person---he had taken a potshot at Gen. Walker too. He was prone to suggestion, and shooting at public figures.
4. In the US, any number of Castro sympathizers were embedded into the Cuban exile community. G2'ers who wanted revenge on JFK for multiple assassination attempts on Castro, and also for booting Russians off the island. Zealots. There was an Alpha-66 house on Harlandale in Dallas. LHO got on the G-2 radar down in MC, or even in NO.
5. On three days notice (from Nov. 19), what sort of JFKAC could be plotted out? LHO had military experience, and likely the G-2'ers also, they were good with guns, but they had limited resources. They devised a good plan, under the circumstances. In fact, the plan worked.
6. Sure the plan was risky. In the old days, guys would rob banks; it was risky. The JFKAC planners were zealots, men of action, but with limited resources. In addition, they may have regarded accomplishing the JFKA as primary, and escape as secondary. Like the Puerto Rican nationalists who shot up the Congress and also tried to assassinate Truman.
7. On three days notice, a couple G-2'ers with guns, and LHO and his M-C, no other real resources in Dallas, what better plan could have you come up with?
8. In fact, the JFKAC worked. Even LHO could have escaped, had he only a motorcycle to his name. Boats were leaving from the Mexican coast for Cuba routinely (this is assuming the G-2'ers would not have waxed LHO too). The Mexico-US border was 1,800 miles long and wide open.
I can't prove this scenario of G-2 and LHO. It just strikes me as the most plausible explanation of the JFKA.
I contend there had to be two gunsels due to the timing of JBC's wounds. I work from there.
Caveat emptor, and draw your own conclusions.
I take no umbrage at other viewpoints.
