What is a potential consequence for a peace officer who knowingly allows impersonation of a peace officer?

The correct choice indicates that a peace officer who knowingly permits someone to impersonate a peace officer could face a misdemeanor charge. This consequence stems from the obligation of peace officers to uphold the law and prevent illegal activity within their jurisdiction. Allowing impersonation jeopardizes public safety and undermines the integrity of law enforcement.

In that context, a misdemeanor charge serves both as a form of legal accountability for the officer's failure to act and reinforces the importance of maintaining the standards required of peace officers. This response reflects the severity of the situation, as impersonation could lead to serious consequences for the public, including potential harm or misinformation.

The other options, while they suggest possible consequences, do not accurately reflect the legal ramifications tied to this specific scenario. Revocation of police powers is a serious consequence and generally reserved for more severe infractions. A warning from a superior lacks the formal accountability measures necessary for such an issue, and the idea that there would be no consequence if it is not reported undermines the responsibility officers have to report and act against impersonation or other misconduct.
