I am not law enforcement, and this is just my opinion, but I would recommend NO, do not submit a tip every time you see someone who looks like either sketch. If people are doing this, it is no wonder there are 30,000 tips and counting, and each tips needs to be investigated--no wonder this case is not solved, if the police are inundated with tips that represent little except someone's desire to become involved with this investigation. My suggestion is that we stay grounded and do not insert ourselves into any official investigation, unless we actually knew something specific. MOO
