Well my Constitution does guarantee due process, the right to assemble, free speech and a bunch of other things. Well actually it puts limits on the govt from imposing on those preexisting rights.
Where does your Constitution allow for summary executions?
Don't know where you got "your Constitution" but here is what our US Constitution says on the matter.
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
