The scariest line was this: "Terrorists and serious criminals will always seek to avoid detection." The fact that in the public eye they're going to be claiming they are doing this under terrorism, will give a lot of weight with non-technical people.
Right. It makes no sense. "Let's bring in a law that logs everyone not seeking to avoid detection." Any serious criminal/terrorist will use a VPN, disposable phones with end to end encrypted messaging, or pen and paper. Any criminal/terrorist that doesn't take these measures shouldn't be a problem to prevent in the firstplace.
Or just plain old stenography in very public forums.
Basically impossible to detect.
