In the 808, the suspects seem to have more rights than the victims. It seems that they prefer you to be a victim first and not be proactive to prevent a crime, then they will start the process to charge the individual. When I was a juror on 3 criminal trials, the instructions seemed like it was skewed against the prosecution. That experience along with Bill Clinton saying " it depends what is, is" has changed my thinking to disregard the old saying " if you're not sure don't do it". As I've grown older I know that is shibai only to control the population.
My own rule is that I'll carry a holstered firearm (pistol) on my property but not pass the property line, unless it's a situation like the guy beating his girlfriend to death on the street with the shotgun or similar. I have the pistol's permit in a neck pouch if I carry outside my house on my land.
I believe you are correct that with the crackdown in Kakaako, Waikiki and other commercial areas, the homeless will spread out to adjoining residential areas. The whole world is being turned upside down in these times. Look how long it took to lockup the crazy Yama Fazarri guy that had threatened people more than once.
