Uhm, I'm sorry, why does this apply only to encrypted messaging apps? What about people in cars? Isn't it about time police had a swift and reliable method to find out what car passengers say to each other? Do we really want to let terrorists and pedophiles use their cars as a safe haven, where they can say whatever they want, and the good guys are powerless to find out? Just recently a terrorist used a truck in an attack - wouldn't it aid police to know what he said while driving?

I also heard almost all terrorists and child molesters talk to others in their homes. There's many reports of terrorists getting together in someone's house to plot and exchange information. I think it's about time we gave the good guys the tools they need to find out what was said in a room. We wouldn't want to leave pedophiles and terrorists any safe havens, would we?

And don't worry about abuse - any time a police officer requires access to the recordings of microphones that will be mandatory in all cars and houses, a judge will have to approve the request, so the risk of abuse is minimal! Only privacy extremists would be against such common-sense precautions.
