Faulty reasoning leads to faulty analysis and unless cooler heads prevail, immoral overreaches.
If the apparently wayward companies being mentioned were to hypnotize or even poison all of their users it would stop all kinds of mayhem from happening. Facebook offing its billion odd users would measurably reduce all manner of crime statistic. That does not justify that action.
Do the police have the right to inspect people's communications and personal material without a warrant? No. No they do not. There is a reason for that. It is clearly a reason they do not understand.
The people in the UK government bleating endlessly about this should be relieved of duty until they become fully clued.
Companies like Facebook do not need any more excuses to spy on people.
