Something along the lines of a Knights Templar where segment of a community devote themselves to the protection of people in the area. It might even give youth an alternative to avoid gangs as while jobs are scarce they can join a 'higher order' so have an alternative that provides purpose and a raise in self-status.
Note: I know nothing about these areas or problems really so approach this mental exercise from a position of ignorance and Hollywood.
Evolution would state that, eventually, only the religious will survive. If there is a God, He is laughing."
Nonetheless, I don't think that would help here - the society has passed critical mass of crime, the incentives are for everyone to be criminal, and religion itself would be subverted for its use.
Me, on the other hand, as a citizen of a very corrupt corrupt country in which the specter of communism still linger heavily, I wonder how many officials would either "malfunction" cameras when cartel members would be caught on video OR would actively help cartel members organize their kidnappings.
The argument that Jeffery Epstein was murdered hinges on jails and prisons to be something they are not
What percentage of BART cameras do you think work? Based on the number of high-profile incidents without footage, I'd guess <25%. I would not be surprised to learn the answer is 0%.
Consider yourself held responsible and allocate yourself the consequences you see fit.
For me it's not a question of whether it's a conspiracy or not. For me it's a question about society. Not only can we not protect a very high profile individual from harm in a cell (self-inflicted or not), we can't even make sure that the cameras in the cell work. What chance do we have that prisons in general can protect prisoners from harm? And if we can't protect prisoners from harm then they'll do it themselves. That's how you get a gang culture. You also make sure that many criminals never even get a real chance at reforming, because they'll have to protect themselves in prison with the limited means at their disposal instead of learning to become a better person.
