That's hardly surprising. I assume C3P is staffed by parents who have lost their kids. One can hardly blame them for trying to subvert privacy. Frankly their presence is a good thing; the more people who lose their kids to creeps, the stronger the social reaction to preventing that should be.
But factually I suspect we're almost as safe as we've ever been, so thankfully, their voices aren't too loud.
It's LPC policy to listen to these kinds of lobby groups, no matter how unhinged they might be.
A significant participant in a lobby group with similar aims, Nathalie Provost, is actually a sitting MP in Quebec.
