The framers of the Constitution envisioned small government, not no government. They certainly didn’t envision a government which would arrest someone and then, despite clear proof that the person had committed a serious crime, set the person free without so much as a note in the court’s or police records about the crime, giving the criminal the opportunity to go on committing such crimes at the expense of innocent citizens. All the criminal-coddling evidentiary rules and Miranda warnings and similar stuff is very modern, and defies common sense. The purpose of laws and courts is protect society at large from the harm inflicted by criminals. If you happen to get hold of two at the same time, one whose crime is knowingly searching without a warrant or other legal right, thus providing proof of the other’s guilt, prosecute both of them.
We have thought and vegetation crimes now.
Soooo...exactly which part a government would you like to shrink?
