I get why this pattern feels suspicious, it really does look like more than coincidence when you line up the cases. But I've gone down this rabbit hole before and honestly the more I dug the more I found mundane explanations for most of them. That said, a few cases do sit uncomfortably with me.
What I'd say is worth being careful about is that sometimes we're drawn to the pattern because our brains are wired to find patterns, especially around powerful people. Doesn't mean every case is clean, just means we should pick the strongest examples rather than lumping everything together.
Which specific cases are you thinking of? If we focus on ones with actual documented irregularities rather than just "timing seems off" it makes for a better discussion. Some of these genuinely deserve scrutiny from investigative journalists rather than being dismissed outright.
