Thanks for this. I guess it could help with the war against terrorism and that may be why Sessions is in favour of it. But yeah, it could also cause financial harm to many people. Kind of like with the whole privacy thing and the government spying on people. It may be helpful for the fight against terrorism but people like to have their privacy. This might also be the main reason why many people in America want to be able to own guns. Then you can have privacy by default because people won't wanna spy on someone who owns a gun? But if it is the government I guess it is different.
