Recently a very reasonable question came-up in a discussion within a private Face Book group.
Does the Coast Guard have the authority to fire on a vessel suspected of running drugs or engaged in some other suspected illegal activity?
The short answer is yes. Unremarkably, the rules of engagement are similar to those of any law enforcement organization.
The US Coast Guard may fire disabling shots at a suspected drug smuggling vessel as long as specific legal rules and operational conditions are met.
Under the Coast Guard Use of Force Policy found in the Coast Guard Maritime Law Enforcement Manual (MLEM) paraphrased as follows:
1. Legal authority (jurisdiction). This requires probable cause or reasonable suspicion of drug smuggling. Including, does the USCG have the legal authority to stop the vessel - is it in US waters, is it a US vessel, or has a foreign nation given permission.
2. Issuance of warnings. This requires the use of visual and verbal signals. The use of lights, sirens, radio calls, and hand signals. And frequently warning shots first; typically with an M240 or .50-caliber across the bow.
3. When the suspect vessel refuses to stop. If the crew ignores repeated commands to stop - called a “non-compliant vessel” - disabling fire is permitted as the next step before any higher level of force.
4. Only to disable the vessel, not harm the crew. These are called “Disabling Fire” or “Engine Disabling Rounds.” Shots are directed at the engines, not people. Only trained Precision Marksmen/Surface (PMS) or helicopter gunners can do this. These shots must be reasonably expected to stop the vessel safely.
5. When the Coast Guard cannot fire. They may not fire simply because the boat is suspected of drug running. If it would create an unreasonable risk to innocent people. Without proper maritime law enforcement authority. Without exhausting lesser means (warnings, maneuvering, etc.)
6. Helicopter Armed Interdiction. The MH-65 “Hitron” helicopters are utilized for this. Using a self-stabilizing weapon they fire warning shots. Then fire precision .50-caliber disabling rounds into outboard motors. This is a standard technique against go-fast boats.
7. Deadly force. Deadly force (shooting at people) is allowed only when the suspected crew poses an imminent threat of death or serious bodily harm. It is unlawful if solely because of drug smuggling or fleeing.
Through Operation Pacific Viper, the Coast Guard has accelerated operations against cartels across the Eastern Pacific.
During this surge, the crew of USCG Cutter Munro only last week delivered a massive win: 20,000+ pounds of cocaine seized in a single interdiction, the largest Coast Guard drug bust at sea in more than 18 years.
USCG crews are bringing every capability to the fight, protecting the Homeland, and combating the flow of deadly drugs long before they can impact American communities.
