It seems a pair of border patrol agents were charged recently with the murder of a Mexican drug dealer. They got long, long sentences, even though their attorney pointed out that in the darkness, they believed the dealer was pointing a weapon at them. I believe he even pointed out that they were doing their duty as enforcement officials. He was also stopped for being in the country illegally.
My comment is that they should have been in New Mexico. Really. Why? Well, we had a case a little while back where a Deputy Sheriff shot and killed a man, who was handcuffed, wounded and laying on the ground. He served less than one year. Western justice is a bit different than other kinds of justice apparently.
