It's been over 30 years, but that reminds me of the 'Miami River Cops' case. Seems having corrupt police in Miami protecting drug traffickers and shipments has been standard procedure for decades:
"Real cops who would go down in history as the Miami River Cops – or as they liked to call themselves, “The Enterprise” – the most notorious gang of corrupt cops ever to don the badge in Miami.
By the time it was all over, more than 100 cops has been arrested, fired, suspended or reprimanded for corruption, coercion and cocaine rip-offs unveiled during the Miami River Cops investigation, including 20 who were convicted and sent to prison."
