Was up at the Stilly above deer creek Saturday. Noticed a couple other anglers fishing above me, and saw one hook up to something. Out of courtesy I reeled my stuff in and traveled up river to see if he needed help or a possible picture. He ended up hooking a bull trout/dolly in which right in front of me he simply dragged it onto the rocks. While it was laying on the ground he insisted on pulling out his tape measure, and began measuring it. Once finished measuring he put his tape away bent down, grabbed the fish by the tail, and slung it five feet airborne and into the water. I was in a bit of shock and did not want to do so I just turned around and went on my marry way. I look back and wonder if I should have said something but you never know if you dealing with a crazy dude who is packing heat. So what would you guys have done?
