Not really. Anyone with a basic knowlage in radio operations would be familiar with the system. The only reason this hasnt happened before is beacuse the people who own the equipment to do this are usually liscened operators with a huge respect for the system. Its actually very uncommon for shortwave operators to abuse their equipment.

Human error doesn't come into place with this?

I don't know the whole situation of how or when but isn't it easily to target such an operator's equipment to use for such an act?
