Unfortunately, yes the police are legally allowed to say just about anything to you while they have in custody. By telling you that your accomplice has already confessed or that they have substantial evidence and key witnesses ready to testify, they are hoping to draw a confession out of you. The authorities already have you pegged as being guilty, so by telling these little white lies they intend to simply speed up the confession process. If you make an incriminating statement, you just made their job much easier and they know have solid proof that you are guilty. Remember this before you think about answering any of their questions and exercise your right to remain silent.
If you did not actually commit the crime, then you may have even more to lose than if you were guilty. People are falsely accused and convicted more often than one would think and it is always better to be safe than sorry. The law claims that you are considered to be innocent until you are proven guilty, but the truth is that the authorities and the prosecution believed you to be guilty since the moment you were arrested; they are just looking for proof to validate their claim. If you are considering representing yourself in a criminal case, take a moment to ponder everything that is at stake. With the help of an assertive legal advocate, you can bet that your chances of success will be significantly higher.
The probationary period is basically an extension of your original sentence that the court is allowing you to serve outside of jail or prison. During this time you are still under the court's supervision and they will be watching to monitor and test your behavior- you may even be required to report to a probation officer on a regular basis. In order to keep your probation you must abide by the terms and conditions set forth by the court- these may include community service, taking random drug tests, treatment classes, abiding by a curfew, remaining in a certain jurisdiction, or obeying the terms of a protective order. If you fail to follow the rules of your probation, then the court could extend your probationary period, tack on additional restrictions or revoke your probation altogether.
