As for this drug bust, what probably happened (because this is how the last 3 of these have gone) is some dumbass thinks he can sell drugs in the dorm and get away with it. Well, he does for awhile and so his buddies get in on the action. It filters in to a couple of bars that are literally across the street from TCU.
The nerds or RA's (or as in the last case bar owners) will notice traffic and or just snitch to people in power at TCU. They contact FWPD. FWPD sends in young looking narcs and these dumbasses assume they're TCU kids and next thing you know 10+ people are arrested.
Most go to drug classes, get probation, and move on. 1 or 2 get an example made out of them
