Covering the faces of suspected criminals

In Sweden most newspapers cover the faces when showing pictures of suspected criminals, but one wonders why they do it if they do such a bad job. I´ll give you an example.

This is an article about a swedish athlete that whent a little off and stole a car and crashed it into the wall of the Royal Palace, seems he is a little to fond of the Crown Princess Viktoria

The article (in swedish)
The masked picture used in the article
The unmasked picture

If they were serious about not revealing the identity of the person they ought to use no picture or do a much better job of masking it, but I suspect they kinda want us to now

They make it even easier when they use their own pictures and qoutes from their own articles
