Nothing negative to the sports of hunting/fishing is going to come of this.
The agents screwed their own pooch by testifying that they witnessed them for 2 hours without noticing them do anything wrong, THEN followed them back to their camp and proceeded to put them through a checkpoint (license, check magazine capacity, and overall search of their belongings). This IS unconstitutional THANK DOG!
At most all this will change is the reason for suspicion claims by the officers in the future. If they had just testified that they "thought one of them shot 4 times" or something like that then there would not be a case against them.
Cops have learned. They pull people over randomly all the time, but they just claim they "smelled something" or "they crossed the line" or "they thought they saw someone throw something out the window". Works every time.
As for the felon with a firearm....If we can't trust him with a gun out hunting then WHY IS HE NOT STILL IN PRISON?
Armed robbery is one thing but his felony may have been writing a 750.00 bad check, or maybe he sold some weed once when between jobs. Do we really assume that a guy convicted of THAT is likely to shoot someone if allowed to go hunting for food? Kinda ironic that he was the one complaint with his permit, plugged magazine and non-lead shot.
