I will agree in general that FIRST students behave better. I've heard it from at least two sources. Our bus driver one year commented that we were better behaved than the usual Cedar Pointe crowd he gets for HS groups. A maintenance/housekeeping worker in Atlanta said the crowd was much better and cleaner than your average NFL crowd.
I'd point out though, that sometimes part of our inherent geekiness (and I mean that in the best sense) involves some anti-social behavior. Individual kids may range from behaviors that are simple inability to deal with others because they are often loners, to ADD and even mildly autistic team members. Add in an "I am always right" component, and you have the scenario for disagreement. It probably won't devolve into a bloody shootout or even fisticuffs, but mentors need to be aware of team/individual dynamics to ensure the team functions harmoniously, at least most of the time.
Oh, and I've found in life that the "good kids" are sometimes allowed to get away with more.
