For several reasons, I will keep this short. But I wanted to draw people's attention to a video on the New York Times website, "Bodies in the Desert", detailing the identification of undocumented immigrants who have died along the border trying to enter the US. There is much in the video that, I believe, everyone should learn.
5 years ago I moved to Tucson. I have learned many things since then. First, the border will never be secured. Second, all attempts to secure the border are merely attempts to manage the border. Third, the current management system is designed to push migrants further into the deserts, into the wastelands. Finally, the deaths of migrants are a direct result of that management system.
You might also want to read the comments attached to the article. There is much wonderful in those comments, but also carelessly hateful comments that, I think, deny even the most basic empathy that any human should have for another.
