Those Who Don't Learn from History are Doomed to Repeat It

Ref.: The entitlement society:

"As Tacitus shrewdly observed, 'Little by little there was a slide towards the allurements of degeneracy; assembly rooms, bathing establishments and smart dinner parties. In their inexperience the Britons called it civilization when it was really all part of their servitude.'" - pg. 252, Saxons, Vikings and Celts by Bryan Sykes

Ref.: Gun control

"The final withdrawal of the Roman army, some fifty years later, left England completely undefended and the population unprotected. Four centuries of occupation, during which citizens and slaves alike were forbidden even to carry arms and all weapons and military equipment were in the hands of the army, had left a population unaccustomed to warfare. That is not to say that the population was necessarily completely defenceless (sic). Everyone must have seen this coming..." - pg. 255, ibid

Here, however, people evidently prepared to some extent to protect themselves.
