who came up with if you see something say something
Allen Kay Since 1992, Kay's agency has been responsible for the New York Metropolitan Transportation Authority's advertising. To give the MTA a human voice, Kay and his team created the "SubTalk" brand[14][15] by which MTA posts messages to riders in stations and on subway trains.[2] He coined the phrase, "If You See Something, Say Something"[16] for MTA's campaign to encourage riders to be part of MTA's security efforts.[17] Since 2002 the campaign has evolved from simple print ads to television spots, increasing the reporting of suspicious packages from 814 in 2002 to over 37,000 in 2003.[18][19] Today, more than 30 transit systems use a version of Kay's innovative "See Something, Say Something" campaign.[17]
Evelyn Beatrice Hall In The Friends of Voltaire, Hall wrote the phrase: "I disapprove of what you say, but I will defend to the death your right to say it"[4] (which is often misattributed to Voltaire himself) as an illustration of Voltaire's beliefs.[5][6][7] Hall's quotation is often cited to describe the principle of freedom of speech.
