I'm sure that they don't need to. They just ask the casinos and other places to give them all the footage after the fact. Wouldn't you want to hold a conference like this in a place where all surveillance equipment were not standard so you can spot them as anomalies in the surroundings? I would imagine that every single person that has attended is on the list of people whose communications are stored indefinitely.
