A High School in Davis could be perfectly functional with OOC restrictions against gun violence and IC disincentivization of crime. Metal detectors, security and the like to heavily discourage melee weapon use. Legal punishment and school consequences (namely, expulsion for repeat offenders) would discourage it just becoming an open center of crime for those who don't truly want to roleplay in a school environment. Media attention from school violence seems like paranoia more than anything, especially considering the amount of violence regularly occurring against minors ingame.
