The law, in all vicissitudes of government, fluctuations of the passions, or flights of enthusiasm, will preserve a steady undeviating course; it will not bend to the uncertain wishes, imaginations, and wanton tempers of men. […] On the one hand it is inexorable to the cries and lamentations of the prisoners; on the other it is deaf, deaf as an adder to the clamours of the populace.

John Adams (1735-1826) American lawyer, Founding Father, statesman, US President (1797-1801)

Speech (1770-12-04), “Argument in Defence of the Soldiers in the Boston Massacre Trials”
