Evidence: Militias are working with the Iraqi Police and Army

"Before you read this, I will tell you what happened Monday to my uncle:

He was going to his work in the morning with his friend and a driver (he works for one of the ministries, I can’t say which one).

Four cars blocked their car, and 16 gunmen stepped out asking my uncle and his friends to come with them, so the gun men started to kick him force him to rid with them but he kept resisting tell them if you want to kill me then do it here, at least my body can be found and identified."
