How do you report racketeering and corruption at a synagogue?

So who do you turn to if a synagogue uses deception, intimidation, false witnesses and even false phone recordings of pre meditated phone calls to frame and to rakateer money from congregates or potential converts, even threats of using arabs or romas to stalk or cause vandalism as well to obtain anything possible and even lying and bribing police to harass their victims

What if someone had videos, phone recordings, photos that proved these people where calling their victims with pre meditated phones calls which contradicted the iphone audio recordings of meetings and clearly showed they where trying to create false evidence to defend themselves in the event they where investigated or presented a case against their own victims for what they themselves did as perpetrators.

Added (1). They have the evidence Josh, so who do you turn to if these criminals are crawling around shuls hiding behind G-d fearing jews who are not aware of this? Who can you contact id they bribe local police, lawyers and judges?

I have a feeling you're just being anti-semetic because your language sounds like it comes from a (badly trained) lawyer who has a real attitude towards Jews. If you have the evidence then take it to the courts and you will surely win!
I don't think you do, I don't think you will and I do think you have problems.

They will call you antisemitic even if your jewish because they want to believe Israel is the indispensable nation,

I answered your questions in the past about your been a Kohen, i would recommend contacting the lubavitcher police about this, there are always some sort of criminals inside religious institutions, Synagogues happen to be the hardest to bust because they syndicate crimes across the world, it may be that the people you met with this evidence have mixed with millionaire non G-d fearing jews who are in the shulls for the money and not to pray, they make a bad name for the communities and need to be confronted by Jewish police, its hard to prove their connections but if there are photos and videos i say share them with a G-d fearing community far and outside the one these people came across.

My life already - get a gentile lawyer

Contact the police.
