My 70+ grandfather, with not the best hearing, drove to his property (former site of the family business, at the time up for sale) one night and saw this guy hanging around the dumpster. So, he drove up to find out what was going on. Well, the guy was a plainclothes cop. He may have quickly identified himself as such and my grandfather didn’t catch it, but he showed no identification and very quickly just pulled a gun on him. The cop was briefly distracted, turned his head, and when he turned it back, he found that my grandfather was pointing a gun at him.
They stared at each other in silence for a bit, and then my grandfather simply drove forward and away. (Fortunately, the vehicle wasn’t aimed at the dumpster.) A short distance away, roadwork was being done and he pulled over to report this guy with a gun to the cops hanging out there…
The exact physical details of my grandfather’s arrest are vague, things happened too quickly for him to take it all in and there were no public eyewitness accounts, but it involved six people with at least one literally standing on him as they put the cuffs on. (A 70-year-old who can’t be brought in without half a dozen cops certainly impressed everyone else in the holding cell!)
I don’t recall any major physical injuries, and he actually managed to avoid charges with the aid of good lawyers and/or calling in some favors (I’m unsure of the details here), but it sure seems like his spirit was broken.
He started showing signs of mental decline a couple years later. He was diagnosed with Progressive Supranuclear Palsy and eventually a diagnosis of Alzheimer’s was added. I can’t swear that the stress of his arrest hastened things, but it’s still my theory.
