The Constitution has to be interpreted loosely, otherwise it becomes a straitjacket. You can't interpret it literally. You can pretend to, and go digging around in 18th Century dictionaries to figure out what 'cruel and unusual punishment' meant or what the 'right to bear arms' meant, but that is all fake really. The Constitution has to be interpreted in light of modern needs, and that's what they (the strict interpreters) end up doing in spite of all their investigations.
