It was an act of Christian forgiveness that brought tears to the eyes of those in the courtroom.

Amber Guyger, 31, a white police officer, had just been jailed for 10 years for shooting dead her black neigbour Botham Jean, 26, whom she mistook for an intruder.

While protesters outside the court building in Dallas were outraged by the "lenient" sentence, the victim's brother took a different path.

Brandt Jean, 18, asked the judge if he could hug his brother's killer.

He then embraced Guyger for about a minute in the middle of the courtroom.
