I don't know which Constitution you have been reading...
Amendment V.
No person shall be... deprived of life,... without due process of law;...
Amendment XIV.
Section 1.... No state shall... deprive any person of life,... without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.
There is a flock of anarchists here on FR that incessantly bleats about the Constitution without ever having bothered to read it.
