I assume considering the size of Def Con the same applies.

Then hacker conferences like defcon have their own volunteer staff of various kinds. These usually are doing crowd control and information, but occasionally get involved in attendee drunken or stupid incidents, usually with lesser consequences to attendees.
Some high profile attendees (NSA head, John McAfee, etc) have their own personal security; goons/volunteers then worked as a buffer between those people and attendees. (I did this for a McAfee event at BSides which was super fun because his armed security were also high on methamphetamine and erratic)
Casually thrown in there at the end! Tell us more?
This is not universal across Europe.
I've been part of organizing computer events in the 5k participant range without any hired security or medical staff. I think it greatly depends on the standing and culture of volunteer work in your country.
Defcon is completely insignificant compared to the scale and size of the events that occur in Las Vegas, there are more people partying on the strip on any average Tuesday.
