Re: Politicians don't understand what they're dealing with...
"while the real criminality online is probably going on very well hidden and away from mainstream services."
The trick is, they don't even need to. Law enforcement is notoriously bad at discriminating between a clear-text harmless joke and a clear-text terrorist plan (often chasing the former instead of the latter; see the Robin Hood case, or the wild-goose chase after the Paris shooting that saw law enforcement going all-out for several days after a couple of innocent tourists who were in the tube at the time, with their cellphones reporting to cell towers approximately following the events ; or that time when an innocent passenger was arrested and kept in custody for 48 hrs because a mate sent him a riddle mentioning the word "bomb" while he was at a train station. Plenty of examples really.).
This blanket surveillance puts us all at serious risk, while letting the crims do their dirty business largely in the open.
