Get those idiots off the road!!!

When will the organisers do something about the idiots that run onto the road and cause chaos during the Tour de France?  Will a rider have to be killed before barriers are put in place?  At the very least there should be more security and police.  I am not a Contador fan, but I applaud him for hitting out at the wanker in green who harassed him.  In fact, I'm all for allowing the cyclists carte blanch when it comes to dealing with these pests.  Maybe the cyclists could go on strike or move their tour to another country (Britain would be nice).  Seriously though, this is a growing problem and something must be done.
