Let's see ... the agent moved into Kerry's path - which meant that Kerry was UPHILL from the agent - and it's the responsibility of the uphill party to avoid collisions - and especially when the downhill party's professional responsibility is to be looking elsewhere for potential threats and not at the dweeb behind him on the snowboard.
It is obvious that Kerry will need a new group to protect him from these unprovoked attacks by the vast right wing Secret Service snowboarding attack machine. So maybe his buddy Soros can start a new one... moveover.org?
This type of event doesn't matter because it won't hit the mainstream media.
In this world, Perception is reality.
Whatever is hammered on in the mainstream media is what will be percieved as reality in the public.
If it isn't hammered on in the mainstream media, then the public won't even take notice of it.
Therefore this is a non event. The public doesn't even care
