Okay, I hear that.
What do we know about previous administrations? Say before JFK?
Was it possible for protesters to get close? What about in the late 1890's? Or the early 20th century? It wasn't all sweetness and light THEN either!
I don't know about those, but I believe from LBJ on there was a greater tolerance of protestors. And I don't remember freeways being shut down by motorcades until Slick was in, but I could be wrong.
