With 538 members of our government bodies making trades at "random", with typical trading intervals, it doesn't seem so outrageous that a few times a year there will be a trade that looks to be made on insider information. I'm not saying it never happens, but I think it's difficult to separate "insider trading" from "getting lucky" when you're talking about 538 generally well-off, active traders. It's like when a CEO offloads stock before it drops and everyone loses their minds. But if you dig in to the story, the CEO is just selling stock on a regular schedule.
