Much time has been spent arguing about the soundness of But in the philosophical literature there is no single such principle; there are many harm principles. And many objections pressed against are objections to only some of these principles. The first half of this paper draws a number of distinctions between harm principles. It then argues that each harm principle is compatible with many other principles that impose limits on the law, including but not limited to other harm principles. The (...) second half of the paper applies the lessons of the first to a number of prominent objections to That principle has been accused of a) being underinclusive; b) misrepresenting the reasons why many act-types ought to be legally proscribed; c) permitting lawmakers to treat people as mere means of achieving their ends; and d) being overinclusive. The paper argues that one harm principle survives all four objections. (shrink)

Many oppose the use of profile evidence against defendants at trial, even when the statistical correlations are reliable and the jury is free from prejudice. The literature has struggled to justify this opposition. We argue that admitting profile evidence is objectionable because it violates what we call “equal protection”—that is, a right of innocent defendants not to be exposed to higher ex ante risks of mistaken conviction compared to other innocent defendants facing similar charges. We also show why admitting other (...) forms of evidence, such as eyewitness, trace, and motive evidence, does not violate equal protection. (shrink)
