This is a point that needs, um, pointed out more.
The observational news on places like reddit was great. Pictures of the events unfolding. Areas where the gunfights occurred were mapped quickly. Blew the news agencies out of the water. There are more regular people seeing things happen then there are news reporters seeing things happen.
The investigational information was pretty crap. Lots of names and pictures of people being tossed out that had nothing to do with it. That said, a lot of it is similar to how the police do investigations, the 'internet' just had less information. We didn't get to see things like CCTV footage and such.
Other then telling people, don't take for granted what you read on the internet, not much can be done about the issue though. Some sites can censor information posted, but the rate information is posted will be faster than it can be redacted. Once a few people read it, they will spread that information too. That doesn't even take in to effect sites that will not censor any information. The fact is, with the camera filled world we live in these days, people are going to do their own investigation right or wrong.
