I've got a lot of connections in the state and I can't get a definitive answer, which tells me a lot. We all know what the cost of attorneys fees are, and this went through several processes before they finally just let it go. I have heard that the individual that was the victim of the allegations only sued them for a dollar because he did not believe that the citizens should have to pay for their wrongdoing, which says a lot about his character.
You obviously don't have great connections, or you wouldn't be so far off in virtually everything you posted.
1. If you do an analysis of the license costs and what the various licenses actually cover, you will find that TWRA is about in the middle of the pack in license costs like they have been for the past 30 years. They certainly aren't the cheapest, but they aren't the most expensive, either. And, you would also find that the states with the cheapest costs are getting directed funding from their state's General Funds. TWRA gets zero from the TN General fund.
2. I don't know the associated costs for defending the lawsuit. But, since it was done by the State Attorney General's office rather that private counsel, I suspect it is much less than you are thinking.
3. And, finally, contrary to your hit piece, there was zero "rogue" behavior on the part of the TWRA officers. They had the statutory authority to be on the property without warrant that was in effect since 1974. It passed TN constitutional muster when it was passed, and had not been challenge prior to this case. And, your US constitutional knowledge is pretty suspect. Under the US Constitution and the Open Fields Doctrine upheld by the US Supreme Court, there was zero legal requirement for the officers to obtain a warrant for that surveillance since it was well outside of any curtilage. When cases like this are worked, they are done with the assistance of state or federal attorney generals. From sitting in a pile of discussions with them on similar cases, there was not a legal reason at the time to obtain a warrant. The officers followed both statutes and court decisions that were in effect at that time.
