I agree with Kalidurga, but I also sadly know that such videos exist*.

They are also most likely illegal to sell or distribute.

In Canada there is a team of the federal police that's investigating those things. To my knowledge, they can always use information if they can figure out the IP address behind it. And they sometimes pose as customers to trace the distributors. Giving a call to the non-emergency member of your local police might lead you to find who to contact to pass them the puck.

Good luck.
