If you're willing to roll the dice on a jury trial with much harsher charges and the prosecutor pushing for the maximum possible sentence, yes.
I've always found it weird that the US forces defendants to accept a trial by jury.
It doesn't. Under the federal rules of criminal procedure, a jury trial can be waived if both the government and the defendant agree that it should be waived. Most state criminal proceedings give defendants an absolute right to waive a jury trial that the prosecution cannot override.
If a jury trial is waived, then a bench trial is held. In jury cases, issues of fact are to be decided by a jury, while the judge oversees the case's application of law. In a bench trial, the judge acts as both the finder of law and the finder of fact. Studies show there are little differences in how the two are applied, but some studies indicate that it is easier to fleece a jury than a judge.
Also, Ravy, most plea bargains come in the form of a document for you to sign and that document contains provisions saying that you waive those rights, what punishment you are accepting, and a waiver limiting your right to appeal. Ergo, you just can't accept the plea, but then turn around and decide you did not waive the rights. It's all or nothing.
