I was just about to make this, and you beat meh to it.
Really though, if it isnt a T escaping solitary before we can get out of armory, its a T going through a teleport in his cell to soccer, or its a T using the vending machine to get into the kitchen. Too many teleports, too many guns, too many secret vents. Its just to damn easy for the Ts, and last time I checked, the challenge of being the T is what made it fun to be on that team.
