There might be something more interesting than a tennis ball in that FedEx package.

File that illicit drug revenue under “miscellaneous.”

That’s more or less the policy the shipping giant FedEx followed starting in the mid-aughts, according to a 15-count indictment filed in U.S. District Court in California on Thursday. According to prosecutors, the company knew the shipping services it provided to two Internet pharmacies ran afoul of the law.

“FedEx knew that it was delivering drugs to dealers and addicts,” said a press release from the U.S. Attorney’s Office of the Northern District of California.

The company didn’t just deny the charges — it said that monitoring packages for illegal substances isn’t its job.

In another words: Don’t prosecute the messenger.

“We are a transportation company — we are not law enforcement,” said Patrick Fitzgerald, senior vice president for marketing and communications, in a written statement.
