My best guess is that the situation in Kosovo is going to devolve so that the introduction of ground forces will be in a peacemaking role, as opposed to directly fighting the Serbian military. Under those rules, the force will be invited in, but will be required to keep the peace. I want to emphasize they will have their standard rifles, machine guns, and other infantry weapons with them. In any situation in which force is used, there should be adequate provocation. In many cases, these bean bag rounds are being used in lieu of real bullets.
Many people think the bean bag rounds produce excessive injury.
However, they are far better than being shot by a 9 mm pistol round. The decision as to which system to use must be made by the officer on the scene, based on what is currently available to him or her. The options may run from pepper spray to bean bag bullets to nets to live bullets. At the present time, the bean bag rounds are as effective as any other non-lethal system available. So, in other words you are saying that, in the case of warfare, non-lethal weapons must be used in conjunction with lethal weapons.
