Abuses by private police forces

Private police, whether detective, security, protection, detention or vigilante, maintain their effectiveness by not obtaining public police power hence not being restricted by constitutional obligations. In many instances these groups carry out their activities with implicit cooperation from public agencies; they are given the right to bear arms, the right to detain or arrest; and their use of violence lead to abuses.
