From Judicial Watch:

Obtained by Judicial Watch this week, the notice is titled “Enforcement Options With Alcohol-Impaired Drivers” and directs the 4,000-plus U.S. Border Patrol agents in the Tucson, Arizona sector to “release” individuals under the influence and “allow them to go on their way.” The document acknowledges that this feels counter-intuitive for Border Patrol agents, but eases concerns by answering a hypothetical question for the officers who have sworn to uphold the law: “If you allow this driver to continue down the road and they kill someone, aren’t you liable?” The answer is no, according to the new Department of Homeland Security (DHS) memo. “There is no legal requirement for a Border Patrol agent to intervene in a state crime, including DUI,” the order says, adding that “therefore there is generally no liability that will attach to the agent or agency for failing to act in this situation.”

This is another example that police and/or the federal government are not responsible for your safety even though they will tell you otherwise in different venues.
