Three Loveland, Colo., police officers involved in the forceful arrest and detention of Karen Garner, a 73-year-old woman with dementia, have resigned from the department.

"I share the community's concerns on this. It hurt to see that," Loveland Police Chief Robert Ticer said of the body camera footage of the arrest during the conference. "I've been in law enforcement 32 years, and what I saw in there hurt me, personally."
