What about if it's GCHQ who opens it in response to a properly  
authorized request?   Or is it your contention that they cannot be  
trusted no matter what governance is in place?

Hint: there's only been one documented case of mass interception and  
modification of traffic in the UK.  Was it carried out by (a) spooky  
people from Cheltenham or (b) an ISP seeking additional advertising  
revenue?  What makes you believe that ISPs are the ones wearing the  
white hats?
