Criminal lawyers use persuasive strategies and techniques, however a trial or negotiation for a plea bargain is not won on persuasive skill alone. Rather persuasion is a method criminal lawyers use for delivering and communicating all the behind the scenes work done on a case. Most of the work done by lawyers for a criminal case is not done in the courtroom. The best criminal lawyers work hard with a team, consisting of other attorneys, experts, and investigators.
Criminal lawyers must build their own picture and story of what happened for their client to win the case. While so doing, they also build rapport with the prosecutor and anyone working on the opposing side, outside of the courtroom. The best criminal lawyers can convince law enforcement or prosecutors not to file charges against their client or to file a much lesser charge, such as a misdemeanor. However, to convince the opposing party not to file charges or plea bargain, a criminal lawyer must have done a lot of work to have preliminary evidence to support what he or she is saying. In essence, a criminal lawyer and a prosecutor (or detective) have what can be thought of as a very informal "trial" conversations in which a successful criminal lawyer will show that he or she has the better arguments, evidence, and stance. Persuasive strategies used by criminal lawyers most effectively start as early as possible, ideally even before charges have been filed.
Though criminal lawyers use persuasive strategies throughout the case, from beginning to end, the work done and every stage of the case is very important. In criminal cases, winning by a lawyer really is a sum of it's parts.
