In the US they use online videos against "sportsmen" all the time.
Sometimes the person in the video makes a mistake and sometimes they know exactly what they are doing.
For instance, earlier this year Ted Nugent was convicted of an offence in Alaska.
He was up filming a bear hunt and winged a bear with his arrow. They tracked the bear and after quite a long time determined that the bear was ok and merely winged. They carried on with the hunt and harvested a nice bear. Unfortunately by winging the previous bear under Alaska law they should have stopped hunting because in the regs when you take a shot at an animal it is considered in your bag limit if you hit it or not. By law Ted's hunt was over the second he released the arrow.
Unfortunately neither he or any of his crew knew about this law as their hunting regs are like Ontario's fishing regs.
Any how, someone saw a video online of him missing the first bear and then harvesting a bear and let the ADFG know about it. Ted was charged with taking game without a license as he only had one bear tag. He plead guilty and paid his fines and did a bunch of public service pieces to air during his show.
So you see anyone can make a mistake and if they aren't made aware of their mistake it will continue.
Even if the guy who posted the vid is only made aware of the error of his ways that is good in my books.
So you see I only want to educate the feller about the error of his ways.
