ok are you nuts?
the cop CLEARLY walked over to TARGET the bicyclist, not the other way around
do you not see the cop leap to the cyclist at the end?
are you a cop protecting another cop?
The officer may have known the fellow from some other encounter or a previous relationship. It looks very like he spotted someone he wanted had to hit and he hit him. If he cannot put that sort of thing away while on duty then he does not have the minimum of professionalism to be an officer of the law.
Are you sure? It looks like the bicyclist must have hit a patch of oil and was falling. The cop, doing his duty to protect and serve the citizens of New York City, was merely trying save the lives of innocent bystanders as well as that awkward bicyclist by trying to catch him before he hit the pavement or worse, the children in the crowd. Unfortunately, the unsafe speed at which the bicyclist was traveling caused both the negligent bicyclist and the kind officer to fall to the ground. Fortunately, the heroic efforts of the police officer saved many bystanders from serious injury. I'm pretty certain that fine outstanding public servant deserves a medal for his quick thinking and heroic actions!
