I believe him to an extent.
He was doing this since the 70sn the US. He made sense about that quote about Escobar fearing her. He literally went against the Colombian govβt with tanks. He killed/ordered kills to the point his own people took him down, though it took years as he had support of his barrio.
I will wait until he releases his documentary to see just how much detail he drops. He said he will have a 90+year old original member of the Cartel on it. May be just more marketing but will wait and see.
One guy who can shed light is Carlos Lehder, but I donβt think heβs ever given a video interview, plus heβs already 75 or so.
