I will agree driving in Mexico is not as safe as driving in the US for many reasons however, while reading this keep in mind that the individuals found were believed to be involved in drug trafficking and that thousands of Americans involved in drug trafficking are killed in our country every year it just doesn't make the news.
Here is a novel idea for the candidates. Lets take just a fraction of the BILLIONS of $$$ we are spending killing people in the Middle East and use it to help our neighbors to the South. Oh I forgot that wouldn't create "uncertanty" in the oil markets which allows the oil companies to make BILLIONS in profits.
Or am I just being cynical
