Lot... that's not mean hhahaha
Granted, people stars to Tap-Dancing and the weapons are set apart. Everybody is very happy and grateful... or is what you think... the weapons factories are closed word wide, the armies are released entirely, weapon research are finalized... Unemployment raises greatly and world wide economy decreases... some ex-military desperate, as there are not enough jobs for every one.
Years passed and there are not even murders... However, you hear an explosion... people almost forgot what was that... and everybody runs in panic... Martians? To obvious.. Some armed animals come to haunt us... Those animals were located at the weapon research facilities... muted from human cruelty research... In just some days, they wipe out the entire humanity... celebrating there wont be animal cruelty anymore.
I wish I could travel to a known location instantly.
