There was a homeless guy living in the gym at Rutgers prior to the late 1990s and it's why you had to show ID to get into any of the gyms/dorms.
Very similar story of:
- he was older
- dressed normally
- everyone assumed he was an assistant coach, grad student etc
They mentioned it multiple times in safety briefings and even at "how to be a club officer" meetings to ensure that everyone participating/involved was actually a student.
So if you are a modern homeless guy, you need a skimmer and cardcloner to get in now? Have there been cases of homeless people hacking hotels/motels?
It's not uncommon. University buildings are pretty open even today. I worked with a homeless guy who was a university employee, so he had a legit staff ID card. He just didn't want to spend money on rent. He knew where the empty rooms were that nobody ever used, where the showers were.
I bet every major university has a few people living/sheltering in campus buildings.
