Derek Chauvin’s defense called its first witnesses Tuesday, pitting its own use-of-force expert against a parade of officials and experts called by the prosecution who have said Chauvin acted unreasonably when he knelt on George Floyd’s neck.

Barry Brodd, of Bozeman, Mont., testified that the ex-Minneapolis police officer was “justified” in his use of force last May and acted “with objective reasonableness.” But he acknowledged under cross-examination that the former officer kept his knee in place while Floyd was complying.

Tuesday capped nearly two weeks of testimony presented by the prosecution. Judge Peter Cahill has said that the defense will probably wrap up this week, with both sides expected to give their closing arguments Monday.

Here’s what you need to know:

  • The trial continued as a Minnesota officer and police chief resigned after fresh outrage over the fatal police shooting of Daunte Wright.
  • Minneapolis Park Police officer Peter Chang, whose body-cam footage was showed for the first time Tuesday, said he did not hear police call Floyd’s detainment a life-threatening situation.
  • Shawanda Hill, the woman who was with Floyd in his car moments before his death in May, said the 46-year-old was “very” startled when police initially held him at gunpoint.
  • The jury watched a short video clip from a 2019 traffic stop in which Floyd asked a Minneapolis police officer not to shoot him.
