Re: Too late
"The thing is that this makes the job easier for the police: Someone has a gun, they are a criminal."
Well yeah, by definition, being a police officer becomes a hell of a lot easier and less risky when your job description is to arrest people who have yet to harm anyone!
Someone uses strong encryption, they are a criminal. (Why would you need strong encryption anyway if you don't have criminal intent?) This makes the job easier for police.
