You were unable to address ANY of those specifically and say yes, those are the best options because otherwise, *my sense of justice* is outraged.
Everyone has a right to life, first and foremost, before any of the 'middle Constitutional amendments.' And just like you insist on preserving the protections of the 'middle amendments,' self defense is the LEGAL mechanism for preserving one's right to life. To think that the right to due process supersedes the right to prevent the crime in the first place is idiocy.
"In all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial, by an impartial jury of the State and district wherein the crime shall have been committed, which district shall have been previously ascertained by law, and to be informed of the nature and cause of the accusation; to be confronted with the witnesses against him; to have compulsory process for obtaining witnesses in his favor, and to have the Assistance of Counsel for his defence."
You're denying the accused all of those rights by killing them in the name of "self defense." "Self defense" is criminal prosecution without access to any of our Constitutional rights.
