I say this as a member of a site that discusses active police investigations, which I enjoy. However, I believe social media, especially the FB groups that pop up have really changed the way many departments communicate to the public now days. Social media while very helpful to get the word out can also cause so many problems to an investigation , specifically damaging rumors or actual information being released that LE did not want out there. It moves lightening fast. It’s hard to reel it back in. Because of this, I think some departments are taking a different approach, lips sealed on most facts or avenues they are going down. IMO
