You posted the wrong section, that one is cruelty to animals. A search warrant isn't needed to confiscate firearms but it is needed to enter into someone's property.
As I understand it, breath tests were ruled as not being invasive into a person's body and thus does not constitute a search. Exterior evidence on a person's body does not require a warrant search. When you start poking people with needles then you run into search issues.
Sorry about posting the wrong statute. This is the right one:
http://www.capitol.hawaii.gov/hrscurrent/Vol03_Ch0121-0200D/HRS0134/HRS_0134-0007.htmThe law says a police officer can confiscate any firearms in plain sight, and the ones surrendered under the restraining order. No search warrant needed.
Also, I can tell you that I have personally had several HPD officers in my front yard with no warrant, after I had told them to leave. They then proceeded to enter my house and conduct a search against my permission. They were sent there by an investigator for the prosecutor's office, who had given them the false information that I had been beating my girlfriend. They left without incident, but my attorney said it was perfectly legal in Hawaii for them to do that.
Also, a few years ago I was arrested at my business property (which I own), with no warrant. This time my lawyer said that was not legal, but they did it anyway. I had pressed the cop for a warrant, but he was quite certain that he didn't need one.
Did you happen to see the latest Batman movie ? I know it's fantasy, but one theme was absolutely correct. That power corrupts. It may not corrupt Superman, but it will corrupt most humans.
No offense, but you sound like a young person with very little life experience. As you get older, you will gain wisdom.
