It would seem that the thought police are on the loose looking for new targets. In a barely restrained clamouring to identify the next serial killer, they are trying to figure out the commonalities between unrelated incidents.
According to German outlet Tagesspiegel (the page is in German, but online translators will do a fair job), US police background researchers are struggling to paint a useful portrait of Aurora Cinema killer James Holmes. He had limited activity on social media - shunning both Twitter AND Facebook (shock, horror!) - investigators have discovered two YouTube accounts and a brokerage account (every red-blooded American has a broker!). He had no LinkedIn account either.
According to other reports, Holmes showed more interest in his AdultFriendFinder account (that's kinda like a clothing-optional Facebook).
Ummm… tell that to the 85% of the Earth's population who do not have a Facebook account - they appear to be in the minority.
Similarly, Norwegian mass murderer Anders Brevik also lacked a Facebook account, preferring MySpace, or as Tagesspeigel puts it, using MySpace made him "largely invisible on the web" - ouch to NEWS Ltd!
There is a growing trend here. In order to be considered 'normal,' not only must you have the LinkedIn profile, the Twitter account and the Facebook page, but you have to be a regular contributor. You must also permit any job interviewer to login to your social media accounts and rummage through for any dirt.
To support this view, the news outlet offers research by Richard E. Bélanger which suggested that adolescents under-utilising social media were in greater danger of depression and related disorders. Of course the research showed that those who used it to excess were equally afflicted, but of course we don't see Facebook addicts committing such crimes.
It is approaching the point where we are no longer permitted to keep our thoughts to ourselves, for doing so will have us labelled pre-mass-murderers.
(You might as well arrest this writer now. My Facebook page is a barren wasteland, I've not tweeted in months, and I pay nodding allegiance to LinkedIn by connecting to - and then ignoring - anyone I've ever met professionally)
