Why are you talking about drugs? We have been talking about guns, but since you insisted on bringing up drugs, which are easier to conceal, drugs or guns, when smuggling them to Hawaii? Drugs are easier to hide as they can be packed into shapes to fit whatever hidden compartments they are put in. They are also hidden in the cargo on shipping containers. Guns, on the other hand, are harder to hide and avoid detection.
Why would anyone want to smuggle guns to Hawaii anyway? Are you thinking about gun nuts doing that if Hawaii bans guns? If privately owned guns are banned in Hawaii, we'd be more alert for smuggling attempts. Don't bring up the UK; it is close to the continent and Hawaii is 2500 miles from the nearest land.
