As far as Luhnow's possible violation of the Joliet Jakes' proprietary information, a lot will depend on employment law in Missouri (presuming that this is the state law applicable to his contract with the 3rds). They have only recently passed "right to work" laws in Missouri, which make the enforcement of non-competes (amongst other things) quite hard to do. They were not in place during Luhnow;'s tenure in STL, though, so I do not know if they would apply here.
With deference to the lawyers out there (i.e. everyone except me), I'm not sure they have much of a case if Luhnow used methods and techniques he learned in the Cards' organisation for his new job at the Astros. If he stole their database, that's a whole other matter, but if he used the technique of creating a database that tracked the things he used to track for the Co-Ards, then I don't think they have a leg to stand on. If Luhnow could move the jurisdiction to Texas (unlikely), they'd laugh this one all the way back to Missouri.
Even then, this is (typically) a civil matter, being the violation of his contract with the Jakes. The criminal justice system (of which there are two separate yet equally important parts) usually can't give a flying fuck about these pissing contests. And when it comes down to it, the remedies available in civil court are negligible mostly. Think about it: what monetary penalty could they calculate to put a value on Luhnow having a snapshot of the Jakes scouting system that became frozen in time? It's not like he wouldn't remember the names of the hot prospects and re-boot his file on them at the Astros; so we're only really talking about the Astros having the same knowledge (sans updates) of middling to to low-level prospects. Hardly the sort of thing that the courts are going to see as having a significant financial impact on the Cards.
So the Jakes defense of this is that they broke into their neighbour's house because his grass was very green and they wanted to see if he was using the same fertilizer. On the balance of wrongs, they are way, way, way on the downside of this one.
