Well, reading the article, it seems reasonable to accept that the guy arrowed a bear in a cage, and tagged it as a wild kill. That part of it is sorta hard to argue against. I don't really believe the Agency folks are gonna go out and lie about something like that; misinterpret stuff on occasion, yeah, but this doesn't sound like "interpretation".
So, having a copy of the game laws is what's needed. I say that because the Texas rule book is quite specific about when and how you can take or not take what animal.
We probably oughta wait for more info before doing a bunch more speculation...
