[Read our latest story on the conviction of El Chapo. He was found guilty on all 10 counts.]

After a lengthy 11-week trial, a jury on Tuesday convicted Joaquín Guzmán Loera, the Mexican drug kingpin known as El Chapo. Mr. Guzmán, 61, faced 10 charges, including leading a criminal enterprise and the importation and sales of large amounts of narcotics into the United States. He now will likely spend the rest of his life in prison.

The trial allowed prosecutors to extensively detail the inner workings of Mr. Guzmán’s Sinaloa cartel, providing unparalleled insight into international drug trafficking. Here are 11 of the most important takeaways, in no particular order.

Corruption in Mexico is worse than you think

During the trial, nearly every level of Mexican government was implicated in bribes, including the presidency. One witness testified that El Chapo paid Enrique Peña Nieto, when he was president in 2012, $100 million in exchange for allowing the kingpin to come out of hiding.

President Andrés Manuel López Obrador’s top security official was said by one witness — and federal prosecutors — to have accepted a multimillion-dollar bribe from the Sinaloa cartel in 2005.
