(KCEN) --- Dallas police shot a mentally ill man outside his house, and the neighbors caught the whole thing on camera.

On Friday, a mother and her mentally ill son got into an argument when officers shot 53-year-old Bobby Bennett and charged him with threatening a public servant.

Bennett's mother, Joyce Jackson, told dispatchers he had a small knife.

The surveillance video shows Bennett standing up, arms to his side when officers shot Bennett in his stomach.
