Re: ???
The Royal Mail, and most other country's postal services have the longest tradition of providing lawful(ish) intercept services.. So their 'Black Chambers', where correspondence between suspected miscreants could be opened, examined, and then sent on. Plus powers to open & inspect packages for illegal stuff, hence why postal services can have some LEA-type powers. I think in the US, their USPS Postal Inspectors have more powers than some other policing agencies.
