I think that technology that can be used to protect people, especially civilians, should be developed. I know that I personally draw the line at weapoms platforms and weapon systems. You may develop and build them with the best intentions in mind ("we're at peace and this system is only a necessary deterrent"), but recent history tells me that once these systems are built and sold, they will be used by someone, somewhere to shoot at other people. Even the oh so pacifist Germany sells a lot of weapons and I think every type of weapon system sold to another country by Germany since the second world war has seen some action.
