Power of prosecutors

The current threat to arrest Trump is concerning but not easy to see because it is Trump. To get a clearer picture assume this is happening to a regular citizen. He was accused of paying hush money to a porn start. This is a misdemeanor and has a statute of limitations of two years. Since the event occurred 7 years ago the prosecutor wants to upgrade the charge to a felony which has a longer statute of limitations. This shows the power that prosecutors have when it comes to going after alleged criminals.
