From Alberto Portugheis:

Re: Catching suicide bombers (April 10): These will increase the use of more powerful bombs that can be sent from a distance, without being detected and without the bomber having to die. Why don’t you propose scientists invent bombs of all sizes, shapes and colours, that NEVER explode? and guns that do not allow bullets to come out? better still, couldn’t scientists invent a method of education that creates politicians and masters (Churches, Banks, Industries, Press, etc), who see that wars, revolutions, violence, terrorism, hunger, injustice, etc, lead nowhere? (except to deepen the pockets of the filthy rich)
