Why, what is the matter with us? Are we going to palliate and excuse a palpable and flagrant outrage on the right of speech, by implying that only a particular description of persons should exercise that right? Are we, at such a time, when a great principle has been struck down, to quench the moral indignation which the deed excites, by casting reflections upon those on whose persons the outrage has been committed? After all the arguments for liberty to which Boston has listened for more than a quarter of a century, has she yet to learn that the time to assert a right is the time when the right itself is called in question, and that the men of all others to assert it are the men to whom the right has been denied?
