At the risk of being "Mr. Sensitivity," it isn't just bad trainers that are part of the problem. Pop culture exposes everyone to a predominately negative view of Muslims and/or Arabs. There's a good film called Reel Bad Arabs (reel, as in movie reel) that addresses representations of Arabs in film. It is worth examining the subtle (and not so subtle) messages that inundate LEO, warfighters, etc. and end up influencing the decisions stakeholders make at all levels. There were films that I watched and enjoyed that, on a second look, were ridiculously prejudiced and no doubt tainted my view of Arabs; I'm sure others have similarly affected.
