A mere technical violation of law, with no evil consequences, and without any claim of title, is followed by nominal damages only. If a person, without permission, steps on a field of grass belonging to another, he is a trespasser, and the law furnishes a familiar proceeding against him; but if he has done this accidentally, and without any real damage, it would be hard to pursue him, unless assertion of the title were thought important. But if the trespasser is an old offender, who from the beginning has broken fences, ruined trees, and trampled down the garden, and now defiantly comes upon the field of grass, insisting upon absolute ownership, then it is vain to set up the apology that very little damage is done. The antecedent transgressions, ending in claim of title, enter into the present trespass, and make it a question whether the rightful owner or the trespasser shall hold possession. Here the rightful owner is the people of the United States, and the trespasser is Andrew Johnson. Therefore in the name of the people is he impeached. This simple illustration opens the whole case. Mere technical violation of statute or of Constitution, without antecedents and without consequents, would not justify impeachment. All of us can recall such, even in the administration of Abraham Lincoln; and I cannot doubt, that, since this proceeding began, the Chief Justice violated the National Constitution when he undertook to give a casting vote, not being a member of the Senate. These were accidents, besides being innocuous. From violation of statute or of Constitution the law ordinarily infers evil intent, and, where such a case is submitted to judgment, it throws upon the violator the burden of exculpation. He must show that his conduct was innocent,--in other words, that it was without evil intent, or claim of title. In the present cause we have the denial of evil intent, with a claim of title. The question of intent raised by the offender cannot be considered narrowly. This is a trial of impeachment, and not a criminal case in a county court. It is a proceeding for expulsion from office on account of political offences, and not a suit at law. When the offender sets up good intentions, he challenges inquisition, according to the latitude of such proceeding. The whole past is unrolled by himself, and he cannot prevent the Senate from seeing it. By a commanding rule of evidence it is all before us without further proof. You cannot shut it out; you cannot refuse to look at it. And yet we have been seriously told that we must shut out from sight everything but the technical trespass. It only remains, that, imitating the ostrich, we should thrust our heads into the sand, and, not seeing danger, foolishly imagine it does not exist. This may do at _Nisi Prius_; it will not do in the Senate.
