Criminal Offenses - As introduced, defines "law enforcement activity" for the offense of criminal impersonation to include operating a motor vehicle that displays logos or decals that give the appearance of being operated by a law enforcement officer or the use of blue flashing lights, flashing emergency lights, or a siren, unless certain vehicle identification requirements have been met; specifies that the motor vehicle being purchased from a law enforcement agency is not a defense to criminal impersonation. - Amends TCA Title 39 and Title 40.
