There have been many times where the T's are sent to do 300 and there will be no CT in there so many T's go into the vent that goes to armory. Sometimes, CT's (Not just derps, many reputable, well-regarded people) will cut them off and kill them through armory vents. My understanding of the rules is that CT's cannot go into vents without physically seeing a T go through vents. Even though in this situation it is pretty obvious where a T is going, the CT does not physically see the T go through the vents. Is it still legal for CT's to cut them off? I feel like it ruins the opportunity to rebel and is a copout for the Ct's.
