How much of the Camarena case’s alleged intelligence links is actually established?

Separate the story into layers: the killing and investigation, the drug organizations involved, and the claims about intelligence connections. Evidence for one layer does not automatically establish another. For each claim, check whether it rests on public records, named sources, or a single person’s account, and whether other reporting supports it.

I’d be wary of treating a compelling narrative as proof. A connection between people or institutions can mean anything from documented contact to an allegation of coordination. Look for the exact claim being made and what evidence is offered for that specific link.

It may help to compare accounts that reach different conclusions, especially on the alleged intelligence role. Note what each one can verify, what it attributes to witnesses, and what remains inference. If a claim is repeated across articles, that still may trace back to the same original source.
