When men take it in their heads today, to hang gamblers, or burn murderers, they should recollect, that, in the confusion usually attending such transactions, they will be as likely to hang or burn some one who is neither a gambler nor a murderer as one who is; and that, acting upon the example they set, the mob of tomorrow, may, and probably will, hang or burn some of them by the very same mistake. And not only so; the innocent, those who have ever set their faces against violations of law in every shape, alike with the guilty, fall victims to the ravages of mob law; and thus it goes on, step by step, till all the walls erected for the defense of the persons and property of individuals, are trodden down, and disregarded.
