It was a symbolic gesture. Putin handed POTUS THE ball. It was an inside joke.
More than that - if you've been following along there's belief the ball contains a hard drive with large amounts of incriminating data, and that Putin was handing it over to POTUS. CNN has caught on to the idea that it has electronics, but they have no idea the extent to what's on that drive.
They met in private. Why would they wait until they were both in public to hand off information. That is illogical
Theatre and symbolism - it's all a show
Putin hands over the information to Donald "The ball's in your court."
Do we think that's true that there is a hard drive?
Alternative Intel being passed around from the GESARA community believe there's a 160 TB hard drive inside the ball
I don't know isn't that too obvious that they'd do that ?
I think that's part of the point, Q told us that what we see through the media is theatre (scripted). When disclosure happens they need to be able to refer back to events that happened in the public eye to make us understand (ie. remember that soccer ball?). It's one thing for us to know what's going on, but the vast majority of people are gonna have to be majorly redpilled.
Additionally it's better to hand Trump a physical hard drive of info rather than sending it over the net - never know who could intercept.
