No matter why the police have arrested you, plea bargains will be a part of your time in the criminal justice system. The prosecution will almost always offer a defendant some form of plea bargain. Of course, whether it is a good idea or a bad idea to accept the plea bargain depends on your specific situation. 

Either way, plea bargains are almost guaranteed to appear. According to FindLaw, the three major areas of negotiation for plea bargains are fact bargaining, charge bargaining and sentence bargaining. 

How can we bargain over facts?

Fact bargaining is the least common variety of plea bargain, and many courts do not allow it. With fact bargaining, the defendant agrees to verify certain facts pursuant to the case in return for the prosecution agreeing to not release other details that may be incriminating or otherwise harmful to the defendant. 

Again fact bargaining is very rare. The prosecution is more likely to offer you a charge or sentence bargain. 

What are charge and sentence bargains?

The most common variety of plea bargain is a charge bargain. Where they charge bargain, the defendant agrees to plead guilty to a lesser charge (like manslaughter) in order to avoid going to trial for a more serious charge (like first-degree murder). 

Sentence bargaining is almost the same as charge bargaining. The only difference is that with sentence bargaining the charge does not change, but the penalties attached to the charge do. So as per the previous example, the defendant pleads guilty to first-degree murder but gets a less-harsh sentence in return for doing so.
