Derp Singularity, Observed in UK
David Cameron pushed by protester in Leeds
This is hilarious and happily innocent. But everyone involved truly deserves a big "Good Job, Everyone!" As you can see in this 'Vine' video, https://vine.co/v/OMmHqp07rxa British PM David Cameron is walking toward his car when all of a sudden some random dude comes flying into the picture either slams into Cameron or almost slams into him. The PM's security detail quickly grabs the guy and Cameron appears uninjured and a little stunned.
Now, unlike planes and projectiles, normal sized humans on foot can usually be observed at a distance. So this seems like a bit of a shortcoming on the part of Cameron's security detail. But actually, it gets better, or worse, as the case may be.
The apparent attacker wasn't some crazy person on par with the American subspecies homo fencejumperus, it was some guy sprinting on the way to the gym. So he seems to have been as startled and shaken up as Cameron was. So he's jogging along on the way to the gym but just because he's so hardcore he's sprinting and he plows into the Prime Minister's entourage.
So basically, oblivious doofus careens into British Prime Minister while hapless security guys in suits don't notice him sprinting at the protectee.
