The "Aloha" Stadium staff has an adversarial mentality and therefore posture.  Some are off duty or special duty cops, so I understand where that comes from.  But, most aren't law enforcement.  They just wannabe, or think they actually are, or worse, have been instructed and programmed to behave as such.
The truly ironic thing is that the law enforcement on duty at the Stadium all are fairly even handed, and exercises appropriate restraint and good judgment.  It's the staff that often goes too far, inflames situations, acts arbitrary and bullying, and causes a sense of discomfort for victims and bystanders.
Some of that is what they're told to do.  Search bags and confiscate food or drinks.  Do the strip search thing for who knows why.  
.But, they own their demeanors while doing it.
Much easier and now days more fulfilling to watch a marquee Pac12 vs. Big 10 matchup on free TV, spend some dollars on good poke, nicely marbled steaks, imported COLD beer, with no threat of arrest.
