So it looks like the Astros/MLB were unable to determine internally how their network was compromised and then contacted the FBI. This seems perfectly reasonable to me.
A guy was completely careless with his password, and a competitor used it to steal information. The analogy to "stealing signs" in baseball is almost perfect. In one case, we laugh. In another, the guy goes to federal prison.
Or to put it another way, I'd much rather the FBI spent it's time prosecuting crimes committed by large companies than screwing over kids like Aaron Schwartz for their minor indiscretions.
Instead, I would look at this as two multi-million dollar businesses engaging in corporate espionage. When seen from that angle, it is exactly the sort of thing the FBI should be involved in.
Is there a federal law that makes doing that a federal crime, and, if so, is there not a federal law enforcement agency besides the FBI that has been designated to exclusively enforce the applicable law?
If yes to both of those, then, sure, there is a good case for the FBI getting involved, because its their job. Otherwise, no, they, shouldn't, because its not.
I'm saying that the act of transforming an everyday action into a federal crime just because unauthorized computer access was involved is a horrible, dangerous system for us to have.
What I cannot get over is how absurd is it that the Federal Government has been able to insert itself so deeply into a problem that doesn't warrant FBI involvement in the slightest. Athletic teams have been cheating for centuries. Sometimes that cheating involves ruined careers for both the cheater and the cheated, and sometimes they involve teams losing money. But what they rarely involve is the FBI. And the only times I can think of when they have involved law enforcement have been narcotics or gang related.
To me, this sounds no worse than various other advantages that teams unethically gain for themselves. That our legal system allows for this particular type of cheating to potentially be a federal crime is frightening. Let MLB handle this internally, and play ball.
[edit: holy shit. I get it. The FBI is acting within its legal right (and duty). This is a moral statement about the law that they are tasked with enforcing.]
