Which of the following is considered grounds for the immediate suspension of a peace officer's license?

The grounds for the immediate suspension of a peace officer's license primarily revolve around actions that pose a threat to public safety or demonstrate a significant violation of legal or ethical standards. Involvement in a felony or misconduct that endangers the public is a clear justification for immediate suspension because it implies a severe breach of the responsibilities and trust placed in a peace officer.

When an officer is involved in serious misconduct or criminal behavior—especially actions classified as felonies—it indicates that they may no longer be fit to serve in a law enforcement capacity. This potential for danger to the public warrants urgent action to protect community safety, leading to an immediate suspension. Such a measure also serves as a deterrent to similar behavior by others in the profession and maintains the integrity and accountability of the law enforcement community.

The other options, while potentially concerning, do not carry the same level of urgency or risk to public safety as involvement in a felony or significant misconduct. Civil matters, failure to complete training, and receiving warnings often allow for more administrative handling and do not inherently suggest an imminent threat to the public.
