Looks like false attribution according to wikiquote. (Why do people feel the need to use proof by authority anyway? Either a thing is right, or it is insightful, but attributing it to dead 18th century rebels does not bolster the case.)

When governments fear the people, there is liberty. When the people fear the government, there is tyranny. Falsely attributed to Thomas Jefferson; first attributed to Jefferson in Gyeorgos C. Hatonn, It's All in the Game: Butterflies, Mind Control--The Razor's Edge (1994), p. 214. A 1912 issue of The American Anti-socialist attributes the re-ordered form, "Where the people fear the government you have tyranny. Where the government fears the people you have liberty", to John Basil Barnhill.
