   (1m)   The duly authorized employees of the department have all necessary police powers to prevent violations of this subchapter.

   (2)   Authorized personnel of the department of justice and the department of revenue, and any sheriff, police officer, marshal or constable, within their respective jurisdictions, may at all reasonable hours enter the premises of any permittee or retailer and examine the books and records to determine whether the tax imposed by s. 139.31 has been fully paid and may enter and inspect any premises where cigarettes are made, sold or stored to determine whether ss. 139.30 to 139.44 are being complied with.

   (3)   The secretary may suspend or revoke the permit of any permittee who violates ss. 100.30 or 139.30 to 139.44 or any rules adopted under sub. (1). The secretary shall revoke the permit of any permittee who violates s. 100.30 3 or more times within a 5-year period.
