What do you mean patrol?

The members of public security joint defense team are a group of people who, under the organization and leadership of police officers, carry out illegal and criminal activities such as patrolling duty, blocking cards, waiting, etc., and cooperate with police stations to maintain public order. There is no power of investigation, trial and punishment, and there is no power to restrict personal freedom. Generally speaking, only public security organs and procuratorial organs have such power. Security defense team members can assist the public security organs in the investigation, but the detention and violence in the investigation are obviously illegal. Fines are also illegal. Only administrative organs can impose fines on violators, and the law does not give the security team the power to impose fines.
