Second problem that people sometimes talk about with military use of non-lethal weapons, and it's actually the reason why in the chemical weapons convention, it's very clear that you can't use riot control agents as a weapon of warfare, the problem with that is that it's seen that sometimes non-lethal weapons might actually be used, not as an alternative to lethal force, but as a lethal force multiplier -- that you use non-lethal weapons first so that your lethal weapons will actually be more effective.
