I think that LE made a huge mistake early on, by not making the public aware of the things they mentioned today. If they had come out initially, and told the public to be aware of fresh injuries, vehicle damage, behavioral changes, and a change in appearance, this would have increased the likelihood of more people calling in to report people who have exhibited these things.
Over three weeks have now passed, and people may not remember certain things, especially fresh injuries that a person has observed in regards to someone else.
I chalked up lack of comment by LE early on, as evidence that they had something solid to work with. I was clearly wrong, and am disturbed greatly by this apparent oversight.
