It comes down to first encounter enforcement, what this means is this.  Officer or Sheriff Kealoha is driving in his car and sees some character setting up a tent in a city/state park or sliver of land.  Kealoha should stop his car, get out and say " What you think you doing bruddah?  You have 30 minutes to move before I make my next round."  30 minutes later if Kealoha sees same guy camping he then makes the individual pack up and move on.  It's as simple as that.  The question that we need to ask is where is this first encounter enforcement?  It's not there and you wanna know why, officer/sheriff Kealoha don't want to deal with it!  They drive by and turn a blind eye and a def ear because it's easier to harass tax paying citizens for misdemeanor offenses than deal with a homeless person, simple.  I witnessed this first hand on Nimitz where there was an actual encampment between east and west bound lanes.  Not 20 yards away a saw an officer stop someone for a minor offense.
