I disagree. This would have still been a massive case if it was the CEO of any other industry, just because of the completely unprecedented nature of the crime (and yes, the fact that it was a CEO). The difference is that there wouldn't be such a loud vocal minority siding with a cold blooded killer, which would have mitigated the circus.
New York would still have the same concerns, especially being the business capital of the world. Companies are based there, businesses have their meetings there, Wall Street is there. A CEO gunned down on the street for the world to see, just cannot stand. You'd better rise to the occasion, lest you become a laughingstock by letting this guy get away with it.
This guy wanted to spread his message, and wanted attention on a psychological level too (his ego) - I believe this was for his own gratification more than anything.
The infuriating mistake they've made is what you, I, and pretty much everyone else is criticizing. They are inadvertently elevating his stature, while simultaneously making themselves look like the villain. This is embarrassing, and Adams bears much of the blame. He's not just grandstanding, but no doubt pulling the strings.
LM didn't need to be flown from Pennsylvania to New York. He didn't need to be transported by helicopter to where Adams was standing. He didn't need to be marched alongside a parade of heavily armed tactical officers.
Their inability to comprehend the optics here is astounding.
