It has been a grim couple of weeks in the US, as multiple acts of politically motivated violence have dominated headlines and sparked fears that a worrying new normal has taken hold in America.
Last Saturday, a man disguised as a police officer attacked two Democratic legislators at their homes in Minnesota, killing a state representative and her husband, and wounding another lawmaker and his wife. The alleged murderer was planning further attacks, police said, on local politicians and abortion rights advocates.
