"This extraordinary power is to be conferred upon agents irresponsible to the Government and to the people, to whose number the discretion of the commissioners is the only limit, and in whose hands such authority might be made a terrible engine of wrong, oppression, and fraud. The general statutes regulating the land and naval forces of the United States, the militia, and the execution of the laws, are believed to be adequate for every emergency which can occur in time of peace. If it should prove otherwise, Congress can, at any time, amend those laws in such manner as, while subserving the public welfare, not to jeopard the rights, interests, and liberties of the people. "The seventh section provides that a fee of ten dollars shall be paid to each commissioner in every case brought before him, and a fee of five dollars to his deputy, or deputies, 'for each person he or they may arrest and take before any such commissioner,' 'with such other fees as may be deemed reasonable by such commissioner,' 'in general for performing such other duties as may be required in the premises.' All these fees are to be 'paid out of the Treasury of the United States,' whether there is a conviction or not; but, in case of conviction, they are to be recoverable from the defendant. It seems to me that, under the influence of such temptations, bad men might convert any law, however beneficent, into an instrument of persecution and fraud. "By the eighth section of the bill, the United States courts, which sit only in one place for white citizens, must migrate, with the marshal and district attorney (and necessarily with the clerk, although he is not mentioned), to any part of the district, upon the order of the President, and there hold a court 'for the purpose of the more speedy arrest and trial of persons charged with a violation of this act;' and there the judge and the officers of the court must remain, upon the order of the President, 'for the time therein designated.' "The ninth section authorizes the 'President, or such person as he may empower for that purpose, to employ such part of the land and naval forces of the United States, or of the militia, as shall be necessary to prevent the violation and enforce the due execution of this act.' This language seems to imply a permanent military force, that is to be always at hand, and whose only business is to be the enforcement of this measure over the vast region where it is intended to operate.
