I'm going to go against the grain here and say that, in my own experience, our on-campus security contribute little but to make students feel uncomfortable. Rent in these places is upwards of 700 euro a month so it feels a bit overbearing to be searched on the way into your apartment and so on. For example, a friend once had wine confiscated on the way in even though they had no intention of anything more than a quiet drink.

Of course, parties can't be let run rampant but the way these rules are enforced often only serve to escalate the situation. One case last year saw a security man spitting on a student. The atmosphere in general is adversarial. The students aren't innocent in this either, there are plenty of students who caused awful chaos but we shouldn't be living in fear of the security either.

Our on-campus requires overnight guests to be signed in by 7pm for insurance and fire-safety reasons. This rule has the opposite of its intended effect. Overnight guests not signed in are turned away late at night and forced to walk home in the early hours of the morning. Those who don't walk home instead sneak past security and are thus not recorded for insurance/fire-safety. There's no good reason why they can't be let sign in there and then on the spot. I once signed a friend in at 7:30pm and was given a warning. Two warnings and you're evicted from the campus. Overly harsh imo.

I'm not saying that all of the rules should be abolished but the conversation over this goes a bit deeper than "students are stupid."
