What are the roles of substantive law?

it's very crucial, and many factors of the crime scene can determine what happen during the crime.

donald trump shouldn’t be impeached. if the alleged action would be impeachable if true, so must be the allegation if false. anything else would give the president the power to distort democracy by calling his opponents criminals without ever having to prove it .for more than a few reasons, more and more americans are beginning to support the impeachment of donald trump or at the very least believe he will be impeached eventually. short of trump trying to establish himself as king, i think impeachment is a very bad idea. i cant believe you democrats' would throw shade on him for reasons that you dont even have proof of. ugh. liberals.
