Dear President Obama: You have many important domestic and international issues before you at the moment that require your time and attention, and the fate of a 71-year-old man in failing health who has been in prison on U.S. soil for more than 40 years for a crime that, by all credible accounts, he did not commit is probably not among your highest priorities.

Pedro Pablo Barrientos came to the United States in 1990 to make a new start in life. Leaving his native country of Chile in South America and arriving in the U.S. southern state of Florida with little money and a broken marriage behind him, he managed to get a job in landscaping at first, then worked at a few restaurants and eventually ran his own pizza joint — a sure sign that you have made it in the USA.
