Like most people, the moment the Norwegian mass killer was named as Anders Behring Breivik, the first thing i did was look him up on facebook.
A Director of Breivik Geofarm with qualifications in micro and macro finance and holding Conservative political views, he lists political analysis as one of his interests and his favourite books are 1984, On Liberty and The Trial. He also lists hunting as a pastime.
The reports are that the attacks were politically motivated and judging by his facebook profile, he does seem a political person.
Anders also had a twitter page here with just one tweet on the 17 July stating 'One person with a belief is equal to the force of 100 000 who have only interests.'
The Facebook and Twitter account were only recently set up which could mean that in a piece of grim pre-planning, he created his social media pages knowing that these would be scoured when he perfomed the atrocities and his name became known.
