Prosecutors in Colorado are seeking a murder conviction for former sheriff’s deputy Andrew Buen, who shot and killed Christian Glass, a 22-year-old man experiencing a mental health crisis, in 2022. The prosecution argues that Buen escalated the confrontation unnecessarily and lacked legal justification for using deadly force. The defense maintains that Buen fired to protect another officer from Glass’s knife. The case has highlighted the need for police reforms focused on crisis intervention and has raised questions about the appropriate use of force by law enforcement.
