Chapter XX: Section 3: Any person or persons, company or association, or any

person in the employ of such company or association violating
any of the provisions of this act shall be guilty of a
misdemeanor and upon conviction shall be sentenced to pay a fine
not exceeding five hundred dollars, or undergo an imprisonment
not exceeding one year, or both or either at the discretion of
the court.

_Provided_, That if any company or association be convicted
under this act it shall be sentenced to pay a fine not exceeding
five thousand dollars.

_Provided further_, That the provisions of this act shall not be
construed as applying to policemen, constables or specials
appointed by municipalities for municipal purposes.

As long as the Kearns act stands--and it is safe to say that it is not likely ever to be repealed--the Pinkerton Detective Agency is effectually barred out of Pennsylvania.
