"God forbid we should ever be twenty years without such a rebellion.
The people cannot be all, and always, well informed. The part which is
wrong will be discontented, in proportion to the importance of the facts
they misconceive. If they remain quiet under such misconceptions,
it is lethargy, the forerunner of death to the public liberty. ...
And what country can preserve its liberties, if it's rulers are not
warned from time to time, that this people preserve the spirit of
resistance? Let them take arms. The remedy is to set them right as
to the facts, pardon and pacify them. What signify a few lives lost
in a century or two? The tree of liberty must be refreshed from
time to time, with the blood of patriots and tyrants.
It is its natural manure."

- Thomas Jefferson (link)
