What is the "charge to the jury"?
The jury is charged with what we call "voir dire," which means "to seek the truth." The jury is charged with finding a verdict. They are read jury instructions; there is a very specific set of laws and rules that explains the elements of the crime in supposedly common phrases. The jury is what's called the "finder of fact." They are charged with determining fact based on the evidence presented, based on witnesses that testified and whether they believe that testimony. They weigh the evidence and they come up with a verdict.
