Poor law enforcement who are not capable of acquiring evidence via a controlled buy. Better give them access to everyone's private messages, that will definitely solve crimes once and for all. My point it: if shouting "I am doing something illegal" in public isn't enough to get law enforcement's attention, how would access to private messages change this?
