Opponents of mandatory sentencing point to studies that show criminals are deterred more effectively by increasing the chances of their conviction, rather than increasing the sentence if they are convicted. In a hearing of the House Judiciary Committee, Judge Paul G. Cassell, from the United States District Court for the District of Utah, described mandatory sentencing as resulting in harsh sentencing and cruel and unusual punishment, stating that the sentencing requirements punish defendants "more harshly for crimes that threaten potential violence than for crimes that conclude in actual violence to victims". A hearing in 2009 heard testimony from the American Bar Association which stated that "Sentencing by mandatory minimums is the antithesis of rational sentencing policy". In 2004 the association called for the repeal of mandatory minimum sentences, stating that "there is no need for mandatory minimum sentences in a guided sentencing system." A 1997 study by the RAND Corporation found that mandatory minimums for cocaine offenses were not cost-effective in regards to either cocaine consumption or drug crime.
