Grapperhouse saw how hard it is to track down child abusers. He was touched by it and he wanted to fix this.
The best solution to track down child abusers fast is to track down their communications.
But I agree with you this might not be the best solution for the rest of the world.
Right. Then as bad actors find out that WhatsApp is backdoored, they move on to some other network, the police agents go on to think "oh, cool, no more abusers on WhatsApp, good job!", leaving the backdoor only for the good people and a bunch of police agents thinking "Now that CP is no longer a threat, what else are we going to use as a reason to keep these powers we have"?
The problem is people like Grapperhouse lack creativity. When they feel powerless they can't think of other solutions than the obvious.
Sommige Nederlandse mensen geloven dit? Ik weet het niet hoor.
