I hate to see anyone in LE defend what those agents did. And I may have defended them before I had all the facts, I don't remember. It may have been legal, but it wasn't right. I have no doubt that higher courts will overturn the ridiculous opinion that LE Officers need a warrant to patrol private property. But that is where we are for now in our state. I don't know how much time those Officers had on the job, but I'd expect more out of rookies. Maybe they had superiors driving what they did; I don't know.
But the bottom line is wildlife enforcement in the state of Tennessee is on hold for the time being because a couple of knuckleheads did something ignorant and some judges who were as ignorant as them decided to make an example of them. I hope those judges don't get a chance to tie the hands of all LEO's, we will really be hosed then.
As to the cost of licenses, below is a link to the TWRA salaries. They have a lot of Directors and Managers. Also, there are about 17 wealthy members on the board. Do they get a salary?
