But it may be the only defense, however partial it may be, that Kaczynski's attorneys have. FBI agents uncovered a trove of evidence in his Montana cabin, including virtual signed confessions and a signature completed bomb.
1 Whenever the Moon, Earth and Sun are aligned, the gravitational pull of the sun adds to that of the moon causing maximum tides.  Spring tides happen when the sun and moon are on the same side of the earth (New Moon) or when the sun and moon are on opposite sides of the earth (Full Moon).
For readers who may not be aware, the Moon provides important timing functions for tides to control Earth processes. Without tides, it is believed that the world's oceans would have almost no life, drastically affecting the food chain for our planet. Science already knows that tides control the behavior and life cycles of shore and sea-based creatures.
