I'm thinking about a few scenarios here. One scenario is a Pablo Escobar scenario, or a Don Eladio scenario if you're a BCS fan like myself: A drug kingpin operating outside the United States, allegedly orchestrating drug dealing in the United States.
Another scenario is the Hassan Nasrallah scenario, where a leader of a Lebanese group considered by some to be a terrorist organization, is allegedly responsible for murders in another country, Israel. There are probably many more examples with other countries, so let's not make this political. Let's take the Pablo Escobar example.
Can the US put the foreign drug kingpin on trial? Say that the US has concrete evidence that the drug kingpin is responsible for crimes in the US, but they haven't managed to arrest them yet. Would it be legal for them to put them on trial in the US without their appearance?
Would it be in the US's interests? What are some advantages and disadvantages of that?
The reason I was thinking about this: As far as I know, in civil lawsuits it's possible to put an individual on trial even if they have completely disappeared to a different country. This is legal as long as they have been served properly, even if they never actually received the notice about the lawsuit. I'm wondering whether the same is possible for the cases above.
