The consequences for people involved in all manner of illegal political activity could not be clearer- DO NOT rely on technology to protect you online or in using telecommunications. It's simply too risky that the police can in future access communications which today they cannot. After all, they target people and keep records of electronic communications for good reasons. Not to make people paranoid, but this is a wakeup call for anyone involved in risky activity. Don't get caught doing something stupid.

Mr Persson added that he had opposed making the photos public because it demonstrated to criminals that police could now unblur pictures, but that consideration and the risk the man could face public humiliation or violence were outweighed by the desire to protect children.
"It was a long discussion," he said. "We can't just sit here and do nothing. We have exhausted all possibilities within police work to find this man ... This was the last step."
