"Fancy now,--only fancy,--the delivery of these wise words at Bow Street; and think how speedily the practical catchpolls would reply, that all this might be very fine, but, as far as they had studied history, the naked story was, after all, that numbers of men had a propensity to thieving, and their business was to catch them; that they, too, had been sifters of facts; and, to say the truth, their simple opinion was, that their brethren of the red waistcoat--though they should be sorry to think ill of any man--had somehow contracted a leaning to the other side, and were more bent on puzzling the case for the benefit of the defendants, than on doing the duty of good officers and true. Such would, beyond all doubt, be the sentence passed on such trimmers in the microcosm of Bow Street. It might not absolutely follow that they were in a plot to rob the goldsmiths' shops, or to set fire to the House of Commons; but it would be quite clear that they had got A FEELING,--that they were in process of siding with the thieves,--and that it was not to them that any man must look who was anxious that pantries should be safe." This is all very witty; but it does not touch us. On the present occasion, we cannot but flatter ourselves that we bear a much greater resemblance to a practical catchpoll than either Mr Mill or Mr Bentham. It would, to be sure, be very absurd in a magistrate discussing the arrangements of a police-office, to spout in the style either of our article or Mr Bentham's; but, in substance, he would proceed, if he were a man of sense, exactly as WE recommend. He would, on being appointed to provide for the security of property in a town, study attentively the state of the town. He would learn at what places, at what times, and under what circumstances, theft and outrage were most frequent. Are the streets, he would ask, most infested with thieves at sunset or at midnight? Are there any public places of resort which give peculiar facilities to pickpockets? Are there any districts completely inhabited by a lawless population? Which are the flash houses, and which the shops of receivers? Having made himself master of the facts, he would act accordingly. A strong detachment of officers might be necessary for Petticoat Lane; another for the pit entrance of Covent Garden Theatre. Grosvenor Square and Hamilton Place would require little or no protection. Exactly thus should we reason about government. Lombardy is oppressed by tyrants; and constitutional checks, such as may produce security to the people, are required. It is, so to speak, one of the resorts of thieves; and there is great need of police-officers. Denmark resembles one of those respectable streets in which it is scarcely necessary to station a catchpoll, because the inhabitants would at once join to seize a thief. Yet, even in such a street, we should wish to see an officer appear now and then, as his occasional superintence would render the security more complete.
