Greta was taking this seriously as a real problem, but the Roberts asshat on the street was joining the protestors in the celebration like he was in the winning locker room after the game. A complete lightweight who had no concept of the problems this is going to cause going forward.
And EVERY network is partially responsible ... they thrive on this stuff to feed the 24/7 news cycle. Very depressing. This is just terrible and will continue now that the responsible organizers see how well their plan worked.
We also live in a country where the college students (who must not need to work to support/pay for themselves) riot and turn over cars and worse when the local sports teams win or lose. And don’t discount the 5 minutes of selfie fame, either. I saw the majority there with cellphones out and filming.
