The Department of State Police finds that an entity may have: A staff of all special police officers; or A staff consisting of both special police officers and special police officers who are also MPCTC-certified police officers and are required to renew their special police commission as specified in this chapter. If an entity employs both special police officers and MPCTC-certified police officers, the special police officers and MPCTC-certified police officers shall wear different uniforms. As police officers and special police officers have different limitations of police powers there shall be a means for a reasonable person under normal conditions to differentiate a special police officer from an MPCTC police officer. Entities shall take measures to prevent special police officers from being identified, by a reasonable person under normal conditions, as a police officer, sheriff, highway patrol, trooper, or law enforcement officer.
