this movie clearly have an agenda and which could be sum up like this represent never and never cross the border ( either physical or metaphorical ) . let shun everything that on the other side with a wall or a fence or something else and let pretend all gringo be evil and satanic and or drug dealer . all that be outside one country border ( and specially u border ) be dangerous and malevolent and people there will hate you and or envy you or try to steal you or something else . the base on true event be only a perverse tag that can be pin on anything to give it some aura of credibility or and in this case and just to help push the film ideology down some naïve throat out there . the perversity of the film lie in the fact that it reduce country and people and all else into very black and white stereotyped category represent mexican into disgust people and mexican police into a bunch of corrupt cop and republicans into the right wing moron and democrat into almost hippie humanist and so forth . be there anything good about the film . i hardly think so and but may be you think differently .
