I believe this isn't the best solution. When you think about, the guy does commit his crimes using a sniper, pretty clean crime if you ask me. I don't think people can really have accurate info on him unlesss he basically shoots inside a mall or something. This will just lead to unnecessary speculations, can't you imagine all the people calling 911 because "they saw the sniper getting ready to shoot?" this isn't the answer, the answer is trying to control the gun market and also, trying to find people with acces to guns as specialized as this sniper. It could even be someone form a government institution, army, etc. Do you acutally think he drives a white van? do you think thsi specualtion is healthy??? How do you think all those people driving vans will feel... Of course I feel bad for the victims but, too bad..this situation is really outta of control and scary... but the truth is that this is the product of this society. Peace.
