From a personal experience ... I was in Key West, Fl with my family and a friend with his children coincidentally on the first or second day of the Mariel boat lift. The people coming in were most likely from the prisons Castro was clearing out. We went to see what was going on and found only a few other spectators. The news media that was there was a Canadian film crew. They asked all of us to get close together so it would appear to be a crowd. Imagine what they could have produced if PhotoShop was around.
