I think it is a highly personal choice to confront, to shame, or to approach politely but inform others about the rule, or to just walk away and fish in peace away from the crowd. It is not the business of this fishing forum to encourage conflicts such as confrontations between fishermen. Leave that to the CO to police the rivers. Call DFO if we don't like it. I say it is a personal choice and perhaps even a situational choice because if you weigh less than 150 lbs and the guy is over 200 lbs, or when you are approaching a group of them, you need to calculate the risk of doing so. Think of your family first (lol). Bear in mind that some of those folks used to serve in armies from their native countries and they know how to treat an 'enemy' approaching them with threats. Let's just respect Rod's choice and each others' choices on how they want to deal with these situations.
