If a drone reaches Romanian territory, then it has either gone off course or (let's hope not) the Orcs want it that way. In both cases, the drone could reach populated areas and kill or injure people. I'd rather shoot it down while the risk is still manageable.The border regions are usually not as densely populated as the inland areas. And even in a democracy, laws can be adapted and / or changed. Then you just have to do it now.
