Pennsylvania Supreme Court issued a decision which overturns its previous ban on expert testimony regarding eyewitness identification.
Sentencing in Pennsylvania is based a combination of factors: facts of the case, age, victim identity, gravity of the offense, grading of the offense, and the accused's prior record score. Prior record score is based on the types and number of prior convictions a person has. A person accumulates "points" on his prior record based on felony convictions, consecutively sentenced misdemeanor convictions, etc. The calculation for prior Pennsylvania convictions is very formulaic and set by statute.
