Definition of "terrorism"

In England I was proscribed for having vindicated the French Revolution, and I have suffered a rigorous imprisonment in France for having pursued a similar mode of conduct. During the reign of terrorism, I was a close prisoner for eight long months, and remained so above three months after the era of the tenth Thermidor.

The threat of terrorism to the British lies in the overreaction to it of British governments. Each one in turn clicks up the ratchet of surveillance, intrusion and security. Each one diminishes liberty. David Cameron insists that his latest communications data bill is "vital to counter terrorism". Yet terror is mayhem. It is no threat to freedom. That threat is from counter-terror, from ministers capitulating to securocrats.
