When you are going through a criminal case, you probably want the whole matter to be over with as soon as possible. Many criminal cases are settled through the plea bargaining process. In some cases, this process is faster than going to trial.
Life after a criminal conviction is likely not anything like it was prior to the conviction. Many people who have been convicted of crimes find it hard to find employment. They often notice other changes, such as people looking down on them because of their conviction. Those changes should be enough reason for anyone who is facing a criminal charge to fight against those charges.
