Don’t know if it is related, but throwing it out there....
Top Pres. pardon that I always think of is Marc Rich. (Is he still alive? Not sure.)
Killed by MS-13: Seth Rich. (not proven, but most of us here I think are pretty convinced.)
Also, heard a new thing on the radio (or at least new to me), a feature where the FBI talks about an unsolved case. Today or yesterday it was about a young aspiring rapper with no criminal record who was inexplicably shot while sitting in his car. IIRC, it happened in LA and was outside the studio of some famous rapper. Not sure about those last 2 details.
Something that has been locked in my mind for perhaps 40 years..I remember a woman once told me that where her husband worked it was common for them to paid someone to take someone out. I haven’t let it out until now. Now it fits with all the other horrible evil we are learning about.
