Witnessed a confrontation this afternoon at 1pm at a bar in the Lower between a group of about 8-10 anglers (same ethnic group) and 2 others. I was 75 yards downstream so I didn't hear the whole thing except for the shouting. But this is what I heard happened when I asked someone later. One angler witnessed someone in this group (who were fishing with questionable ethics such as ripping at the end of the drift) in the midst of retaining a wild coho and he told the guy he should put it back in the river right away. The angler with questionable ethics went on a tirade and started shouting profanities and became aggressive towards the guy who told him that he should put the wild fish back. Another man who was out for a walk with his 2 toddlers asked the angry guy to quiet down with the profanities because of the kids to which the response was more aggression and shouting and the 2 went face to face with the angry angler picking up stones with the intent of hitting the father with it. So at this point, it was like a gang of 10 angler buddies vs 2 other guys so the situation got diffused when the 2 guys left the group of anglers alone. As the dad walked past me, I could hear him apologize to his kids for having to hear that. To me, this group of anglers seemed quite threatening and it is almost like a situation where the police should have been called once threats were made. In any case, most of the group left shortly after that as well.
