who shot john lennon

Nobody can prove it either way but you have to ask who had the most to gain?

He was creating a god like-following and there were millions around the world who would hang on his every word.

Whoever it was they were most certainly evil as John Lennon spread messages of love and peace, near the end of his life he began to speak out against the corruption in government and he would bring attention to the people in the world who would manipulate situations around the globe for profit in money, power, natural resources and most of all controll.

Put it this way - I would say the conspiracy theories ARNT "theories" .
