their personal values of privacy rather than to participate in illegal activity. Trade-off between security and liberty Polls analyzed the trade-off between security and liberty. A June 2015 poll conducted by Gallup asked participants if the US should take all the necessary steps to prevent terrorist attacks even if civil liberties are violated. 30% of respondents agreed: 65% instead said take steps, but do not violate civil liberties. In a 2004 Pew poll, 60% of respondents rejected the idea of sacrificing privacy and freedom in the name of security. By 2014 a similar Pew poll found that 74% of respondents preferred privacy, while 22% said the opposite. Pew noted that post 9/11 surveys revealed that in the periods during which prominent incidents that related to privacy and security first came up, the majority of respondents favored an ideology of "security first", while maintaining that a dramatic reduction in civil liberties should be avoided. Events often caused Americans to back allow government to investigate suspected terrorists more effectively, even if those steps might infringe on the privacy of ordinary citizens. The majority of respondents reject steps that translate into extreme intrusion into their lives. Various administrations claimed that reducing privacy protections reduces obstacles that anti-terrorism agencies face attempting to foil terrorist attacks and that fewer privacy protections makes it more difficult for terrorist groups to operate.
