Maybe they are putting these pics out knowing full well that they are not suspects and they already have the real suspects either in custody or are on their trail. This release could be a bluff. Wouldn't be the first time.
I don't mean to come off as dismissive but the article seemed to be talking about communication within a team or with customers and users in a face to face environment. Being able to post on a blog well is not going to get you very far talking to project owners/users to understand business problems. I think social media has an extremely limited usefulness when it comes to determining how well someone can communicate within a real world face to face business environment. I would rather rate a potential employee's ability to communicate on the 15-30 minutes I have to talk to them rather than their social media footprint.
