What the $#@! is wrong with your reading comprehension? Why do you make me repeat $#@! like 50 times?
I know she wasn't a guest, but the rules say common areas are for (specific purposes listed) - Sleeping is not a specific purpose that was listed.
If a student started sleeping in the common area on a regular basis, they would be breaking the rules and the dorms would ask them to stop, because it is against the rules.. If they fell asleep accidentally studying once in a while it likely wouldn't be a problem.
If you look up other colleges and Universities, it is very common for them to say that sleeping is not allowed in common areas - which gets back to my next point - if a white person gets the rules wrong, it doesn't make them racist. You are making a non-argument. Even if sleeping was allowed in that common area, if the girl thought it was against the rules and she calls the cops that doesn't make her racist. She would have called the cops if there was a shady white person sleeping in the common area too.
The point is this is all being made about race, but NONE of the people calling the cops are racist. They are just calling the cops because rules are being broken and they fear for their safety of enforcing them themselves.
