May have been ISIS supporter

Law enforcement sources say Thompson had ties to a radical leader who has advocated violence. His Facebook profile apparently shows an Islamist fighter as the profile picture. Comment on a Youtube video:

If you’re looking for ‘perfect’ Muslims who never make any mistakes in their Jihad, then you will be looking in vain! If the Zionists and the Crusaders had never invaded and colonized the Islamic lands after WW1, then there would be no need for Jihad! Which is better, to sit around and do nothing, or to Jihad fisabeelallah!
