Father of Dallas gunman: 'I love my son but I hate what he did'

The father of Dallas gunman Micah Johnson has spoken out for the first time saying: "I love my son with all my heart but I hate what he did".

James Johnson broke down in tears as he said: "I don't know what to say to anybody to make it better. I didn't see it coming."

In an interview with The Blaze, Johnson's family said he was a "good son" but something in him changed after he went into the military.

He went on to kill five police officers at a Black Lives Matter rally after allegedly declaring he "wanted to kill white people, especially white officers".

Johnson's family said he never showed any outward sign of hatred towards white people or other social groups.

"What he did hate was injustice," his mother Delphine Johnson said.

She revealed her son actually wanted to become a police officer at one point before deciding to join the military.

"The military was not what Micah thought it would be. He was very disappointed," she said.

"But it may be that the ideal of what he thought of our government, what he thought the military represented, it just didn't live up to his expectations."

Johnson was killed after a stand-off with police on July 7.

Bomb-making materials, guns and a bullet-proof vest were later found at his home leading police to believe he may have been planning a bigger attack.

Police chief David Brown said the recent deaths of African Americans at the hands of police may have "fast-tracked" his plans.

Philando Castile, 32, was shot dead by a police officer in Minnesota after being pulled over in his car for a broken tail light.

A day earlier 37-year-old Alton Sterling was shot dead by police in Louisiana at point-blank range after being tackled to the ground.
