Where Was Security ? Crazy Fan Interrupts Sox & Yankees Game At Fenway

The one question I have after learning of this crazy fan is "where was security?" Seriously - There's no one allowed into Fenway and this guy - who clearly has been partaking in some form of inadequate behavior - climbs into the stadium and stops the game with a tirade and tis is funny at first but then you have to ask yourself - whats up at Fenway - How did he get in and what happens if he had a weapon????
