Villas - How can one work for the Coast Guard, being a local to the area, sworn to take an oath to protect and serve and have people selling and doing drugs right in their own home with kids in the house? Can't pick a side, even with your family. Turn them in or somebody else will, because if you know they are selling a drug that is still technically illegal and making a profit off of it and you know about it, you will be charged and lose your position.
