Think about this folks. Whether intentional or not, this is great!
If the President hadn't done this, most likely I and many others would have remained ignorant of the crime.
The convicted man is not a citizen. I do not know his legal status in the United States. Whatever it is, this will cast a lot of light on people who come to our country from elsewhere and commit heinous crimes. This will put more attention on immigration law and border protection, which certainly needs more stringent regulation.
What is being done is proper procedure. If this was one of our guys in another country, we'd be up in arms if correct procedure wasn't followed, or at least I hope so!
There can be no bad outcome from this unless the Mexican government fails to handle this properly. They will be watched carefully and if they do great, that means a more peaceful outcome all around. If they fail, they only stress to American citizens that we need to fight for stronger regulations to help keep us safe from crimes committed by foreigners. We have enough criminal citizens to deal with already. The time, expense and insult of having to have our people molested by foreigners and go through the justice system is downright outrageous.
