Where popular elections occur for municipal chiefs of police, county sheriffs and state police heads or even tops of national police forces should they ever happen, such popular elections will alternate cycle to cycle with appointments to the same by an associated legislative and/or executive body or appointments originating from within the law enforcement department. The appointments should occur not too long after the seating of that election cycle they take place in. The appointing bodies may first choose whether or not to appoint the current sitting official with respect to any applicable limit of terms.
Because law enforcement has such direct contact with the populace while carrying the ability to use force upon the people, an alternating cycle between appointments and popular elections of the law enforcement heads will incur some checks and balances by both popular and institutional biases.
Nonetheless, it will be between the constituency and the governing branches of a particular jurisdiction whether to invoke alternating popular election of law enforcement heads where only appointments take place now. Invocation can occur when appointments or even the general practices of the law enforcement body are deemed not to be sufficiently responsive to the serious and valid concerns guiding the popular elections of the determining, overseeing or in-tandem governing officials especially in regards to law enforcement practice.
