You pretty much have to take it for what it is. Entertainment. They did everything they could to elicit a response, drove around for who knows how many days and ended up with about 30 seconds of tape that they could play up for TV. Maybe they should have gone to Bagdad and wrote
I Hate Allah on the side of their Mercedes and see how long (in minutes) before they got shot. Ultimately, if you think that's an accurate representation of life in the US, then the joke is on you.
Personally, I thought it was funny. They got exactly what they wanted, then acted surprised. Well duh!!
