Even if you just assume guilt it doesn't make sense. You send the coast guard to capture the boat and then you have a person with knowledge and drugs and a boat which can be traced & used as evidence...
I actually agree that we ought to be using due process aswell, but I dont like the "these are innocent fisherman" narrative
You mean the casual sense of "innocence", but they are literally innocent in they they've not been convicted of the crime they were killed for allegedly committing.
