[Miyagi-verse] Why DOESN'T anyone call the cops?

Okay, so Daniel and his wife tried to get a restraining order one time, but there's like 40 years of problems here that I think a judge and jury would like to know about. Kreese encouraging his students to kill, steal, vandalize, rob, and disregard any moral system is a serious problem. He even strangled one of his own students after the first All-Valley tournament, with several witnesses standing around doing nothing until Miyagi himself shows up. This whole world seems like it would have a lot less problems if they just tipped legal enforcement off about what is basically a cult leader radicalizing teens.

Until the fight at >!the school, much of what transpires between Miyagi-Do and Cobra Kai can be chalked up to teenagers being teenagers.  Teenagers do dumb things.  Teenagers fight.  Unless there's major property damage or grievous bodily injury, the cops aren't likely to get involved as thoroughly as we might perhaps want them to be.  Even the cult-ing could be described as hearsay, and this is addressed at even the meta-level; nowhere is it shown that Kreese is directly telling Cobra Kai students to steal snakes or break into mansions, so for all even we know - let alone the police - the kids are doing this all of their own accord.  And dealing with juvenile suspects compared to adult suspects - even at the felony level - is an absolute motherfucker in terms of legal process.!<

>!But note that after the school incident, the police are involved; one Cobra Kai student is put in juvenile detention and released only because she's her mother's sole caretaker, a Miyagi-Do student is explicitly on the lam and later arrested after kicking a Cobra Kai over a second floor railing, and a protective order is taken out against Mrs. LaRusso (which, AFAIK, is a two-way street; she can't do anything to Kreese, but Kreese violating the terms himself could render it null and void).!<

>!As for why it took as long as it did to reach this point, there's a bevy of reasons.  Much of what happens could easily be handled without law enforcement intervention until the aforementioned school fight.  Much is made of Johnny and Daniel's egos and pride; maybe it's just as important that they solve the problems facing their students as solving the problem at all.!<
