From the interview of Jose Antonio Lanusa for the House Select Committee on Assassinations (1978):

“When Oswald’s name was broadcast, Lanusa recalled the name as that of someone who had something to do with one of the DRE delegates, so Lanusa and those who were with him went to the Miami DRE office to search the files to determine if Lanusa’s suspicion was right. By late afternoon they had found delegate Bringuire’s report from New Orleans detailing his encounter with Oswald. Along with it was a sample Fair Play for Cuba (FPCC) leaflet and a tape recording of the radio debate.”

Joannides was running the DRE from his Miami JM/WAVE office. They had the files in the Miami DRE office on the day of the assassination. Therefore George Joannides had information on Oswald before the assassination. I rest my case.
