I don't think it is irresponsible on the police's part to NOT release the picture. Why let the guy know they are on to him? He might try to run for it and they'd lose everything. I for one do not believe they need to tell us everything they're doing to catch this killer because I'm sure he watches TV too! I'd rather he stayed fat, dumb, and happy until they come knocking on his door! They won't do that until they think they have enough to indict him, and they won't want to do anything that will allow this guy to get off on any technicalities
