I hate to disturb all you bleeding heart liberals, but there is a simple statistical fact here: for three people to commit suicide on the same night, out of spontaneous, independent desperation, is a blinding coincidence. It seems pretty clear that these suicides were planned.
Having said that, the US rhetoric about an "act of war", driven by a half-conscious analogy with suicide-bombing, is disingenuous. You might as well call Jan Palach a terrorist. Perhaps the three deaths were planned as a protest against the Guantanamo regime. If so, as holding people indefinitely without trial is indeed unjust, cruel and totalitarian, it is hard not to sympathize with their point.
