It should be unconstitutional for officers of the law to kill unarmed citizens. Please amend the constitution.

I'm asking for a revision of our constitution. It does not protect the average American citizen from the use of excessive, lethal, or deadly force to resolve citizen/police conflicts. Police officers have an array of non-lethal weapons but choose to murder unarmed citizens as they deem necessary. This murder with no trial or conviction is unconstitutional and should be out-lawed. Without amending the constitution to provide protection to vulnerable citizens, our lives are in the hands of officers who are authorized to be the jury, prosecutor, and judge when facing confrontation on duty.
