The incident was called the Ruby Ridge incident. It refers to the 1992 standoff in Idaho involving federal agents, Randy Weaver, and his family.

Name use

People usually shorten it to Ruby Ridge rather than saying the full “Ruby Ridge incident”. In some contexts, you may also see similar phrasing like “the Oxford Incident” for a different historical event in Mississippi.

Quick note

If you meant a different state-specific incident, the exact name depends on which state you were referring to.
