Like this: even though the defendant has not stepped foot into the country where the crime scene occurred, but are a third party accessory (maybe ordered the perpetrators to commit murder? maybe they abetted the perpetrators?) but don’t inherit the same passport or nationality.

There’s already a form of punishment from visa requirements meaning if the defendant has a passport from a “third world” country: their travel movement is restricted making any potential vacations a headache, but that alone doesn’t work if the defendant has a strong passport.

Regardless, the defendant hasn’t even been to the country in person where the crime took place but are considered a suspect due to their interactions with those on the ground who executed the crime in where it occurred. I mean, can you still subpoena a foreigner in absentia?
