You forgot the real option. Which is supporting reasonable sentences focused on rehabilitation.
There are very few offenses where a human deserves to be locked up for 20 years.
Also let's not pretend you wanted to imprison them indefinitely. You wanted to deport them, mutilate them, and dump them on a poor nation. You either didn't care or think about whether or not these African nations want our criminals, but what they think doesn't matter right? As long as you hurt the right people?
That's not even getting into the American centrism that assumes people in Africa know all about the American civil war
So repeating your points is "going off the deep end"? Sounds like you were already there
