A criminal defense attorney seeks to exclude evidence obtained as a result of police misconduct. At times, police misconduct occurs in searches that take place during ordinary traffic stops or in a suspect's home. Additionally, if law enforcement is too aggressive in trying to obtain an incriminating statement from a suspect, it may violate the suspect's Miranda rights. Litigation in the criminal court allows a defense lawyer to protect his client's rights by submitting motions to the judge seeking to exclude the recovered evidence or received statements from trial. Often a successful motion to suppress evidence cripples the prosecutor's case, causing the case to either be dismissed or substantially reduced in plea negotiations.
