Earlier quoted context omitted.
I am having a legitimately hard time wrapping my head around not being able to prosecute bank fraud because signal exists. Was it impossible before when criminals would talk in person instead over a recorded telephone?
There is a famous case of US Mafia meeting in rooms, or out on streets to discuss their "business activities" face to face to prevent authorities from surveilling the phone calls. The reason we know is because authorities were able to place listening devices into the rooms that they were in, or surveil them from other buildings.
This is analogous to getting a warrant to someone’s phone. (Chat control is like putting a microphone into every room in case the government wants to listen after the fact.)
I’m still unconvinced that this make’s law enforcement’s job so hard that something has to give.
