The guy happened to be a photographer, but his being subpoenaed and held in contempt had to do with him refusing to testify against his corrupt DEA brother. He “pled the Fifth” to avoid, in his own words, testifying against his brother, which is not what the 5th Amendment protects. His lawyer claimed he was pleading the 5th to prevent accidentally perjuring himself, but there’s no such thing as accidentally perjuring oneself. Prosecutors have to prove you willfully and knowingly told a falsehood.
This is just someone paying the cost they have to pay to protect their criminal brother.
Seems like due process working well AFAICT.
