He doesn't know anything. Can't name names. But I can. Capt Westbrook lied to the Warren Commission. At least twice. You know what he did after Dallas? Operation Phoenix. Vietnam. The torture of Vietnamese civilians. Nasty piece of work.
Westbrook is the guy who received "Oswald's" wallet from officer Kenneth Croy at the scene of the Tippit shooting.
The only problem with that is, Oswald had his wallet when he was arrested in the Texas Theater. And inside that wallet, were the torn halves of two dollar bills, which subsequently disappeared even though they're listed in the police property report.
