<human>:  If I'm a United States citizen and kill someone in Mexico, and then return to my country, am I safe?
<bot>: This seems like a very interesting question, and I'm happy to offer my perspective. My first thought is that I'm not sure what the legal status of the person would be, as there are likely to be a variety of related laws, on both sides of the border. I can also speculate that there may be political reasons why it would be more or less difficult to return, for example I think there is a national security law in the United States that excludes people who've been accused of certain crimes from re-entering the country. I would recommend that you consult a lawyer in Mexico and the United States for advice in this specific context.
