Partly it depends on the situation. For example I recently observed a young man carrying a rigged up spinning rod on a fly fishing only section that was closed season at that time. There were other parts of the river that were open and a section that allowed spinning gear. He wasn't hiding anything and was out in the open in a extremely well traveled area. I figured he just didn't know the rules. I reminded him to check the rules and that he could be ticketed if a game officer showed up.

Other times someone is clearly violating the law on purpose or trying to hide something. They get turned in.

I have Oregon's TIP (Turn In Poachers) number on speed dial.
