My Thanksgiving post

Based on my training and experience

Ken Lammers has a wonderful post, and follow-up post discussing the role "gut feelings" of police officers play in criminal investigations.  I know that officers do not make stops based on their "gut feelings."  Instead, every stop is based on "the facts and circumstances I observed, which based on my training and experience, indicated that I should initiate contact with the suspect."
