Talking Depop

Last year I participated in a conference for the 400th anniversary of Francis Bacon's Novum Organum, organized by the Institute of Physics in Wales. One of the leaders was a guy who does encryption for MI5/6. One day the conversation turned to current events, and he asked me if I had any ideas. I knew his credentials so I said, "anything I say would be speculation, I'm not privy to those conversations." He said, "well sometimes we like to hear speculation," so off the top of my head I said "maybe surgical sterilization? I would rather get cut than get this vaccine, whatever it is. I think the people have shown they will cooperate, they are amenable to instruction. But to do something like this underhandedly..." and left off there. 

Well, the next day my dog came home branded on his groin. I live in Mexico, we have neighborhood dogs that are all a big friendly pack, so mine run around outside. There is no chance that some random person picked up my little daschund and branded him on the groin, the day after that zoom call. ??
