so what was the reasoning for finally letting you in?
this is not very recent but I would think it is still applicable.

it appears that California does provide criminal statutes for this sitaution IF;
the person(s) delaying you are apparently guilty of a misdemeanor even though they eventually allowed you in. If the police refuse to act, I would go directly to the DA's office to file charges.(d) As used in this section, "guide dog" means any guide dog or Seeing Eye dog that was trained by a person licensed under Chapter 9.5 (commencing with Section 7200) of Division 3 of the Business and Professions Code or that meets the definitional criteria under federal regulations adopted to implement Title III of the Americans with Disabilities Act of 1990 (Public Law 101-336).
Not sure what you mean by "no time limit". There is no time limit involved. Either he intentionally interfered or he didn't. There is no requirement for some specific period of interference, just that he did interfere.365.6. Interfering With Use of Guide Dog--Misdemeanor.
(a) Any person who, with no legal justification, intentionally interferes with the use of a guide dog by harassing or obstructing the guide dog user or his or her guide dog, is guilty of a misdemeanor, punishable by imprisonment in the county jail not exceeding six months, or by a fine of not less than one thousand five hundred dollars ($1,500) nor more than two thousand five hundred dollars ($2,500), or both.
I believe he is also subject to federal laws regarding this. this is the link for the fed ADA info:

I believe you may also have a civil action against the individual and quite possibly the organization he was employed by. Call an attorney that deals with civil rights violations. I would think there are myriad sources for such litigators from any organization that assists people with disabilities.
