Private Security Forces, aka DPS

Marquette University has a security force which is called the Department of Public Safety, DPS for short. The purpose of this force is to ostensibly protect the student body, which is surely why all of the officers need to carry semiautomatic pistols with them. DPS has over 400 cameras on campus, and in the campus area. Which is a wonderful thought, a private security force, which does not answer to the public, which has little to no oversight, having 400 cameras monitoring the movement of students and those who live in the general neighborhood of the university. Meaning that if one were to walk within a roughly 4 block radius of the heart of campus, 14th and Wisconsin Ave., one would be continually monitored, even though a majority of that radius is not the property of the university. Privacy advocates should take issue with this, but then again, privacy does not exist at private universities. Moreover, DPS admittedly uses these cameras to monitor the Marquette area for any and all criminal activity. Sure it's great to have friendly people with pistols monitoring your every move to see if you get mugged. Sounds like a great idea, until they illegally enter into homes to arrest people. Go outside of their legal bounds in order to "detain" people suspected of crimes until they are arrested by the Milwaukee Police Department.
Students at the university fail to realize that under Wisconsin State Law, Marquette's Department of Public Safety, cannot be a police force. It has absolutely no legal jurisdiction whatsoever. It can only act under the guise of cititzen's arrest, meaning that I and you have exactly the same rights as DPS does. Unless of course you are on MU's property, at which point in time it has a lot more rights. However, DPS acts as if it is a real police force. They drive around in faux police cars, with lights, they carry guns, have the police like laptops in their cars, and interrogate suspects. They admit to investigating crimes, which is of course illegal in Wisconsin.
So the next time a DPS car rolls by, just make sure you're not committing a felony, disorderly conduct, assault and/or battery, 4th degree or greater sexual assault, drunk driving, or illegally firing a weapon, and you're perfectly fine, because no they cannot stop you for violating open container laws (a city ordinance) or public drunkenness, or whatever you may be doing, such as sitting in a parked car (which happened to yours truly, in which I was asked by DPS why I was sitting in a parked car on a street, I happened to be wating for a roommate to show up to sign my lease).
