WASHINGTON (AFP) - Reforms to United States (US) surveillance announced by President Barack Obama have failed to reassure most Americans, with three-quarters saying their privacy will not be be better protected under the changes, according to a new poll.
By a margin of 73 to 21 per cent, Americans who followed Mr Obama's speech last week on the National Security Agency (NSA) say his proposals will not make much difference when it comes to safeguarding privacy rights, said the Pew Research Center/USA Today poll published on Tuesday.
The poll of 1,504 adults, carried out between Wednesday and Sunday, showed the speech was not widely followed by Americans and that scepticism of the NSA's electronic spying is growing.
The survey said half of those surveyed heard "nothing at all" about Mr Obama's proposed measures and another 41 per cent said they heard "only a little bit". And fully seven in 10 poll respondents said they should not have to give up privacy to stay safe from potential terror attacks, the poll said.
A majority of 53 per cent now disapprove of the NSA's collection of telephone and Internet data. In July, 50 per cent approved and 44 per cent disagreed with the surveillance programme.
The shift in public opinion follows the explosive leak last June of NSA documents by former intelligence contractor Edward Snowden, who has sparked a global uproar over the US government's far-reaching surveillance.
Nearly half of Americans, 48 per cent, said there are insufficient limits on what telephone and Internet data the government can collect, while 41 per cent said there are adequate parameters on the government's spying.
The survey revealed a division over whether Mr Snowden's unprecedented disclosures of classified information have damaged the country, with 45 per cent saying the leaks have served the public interest and 43 per cent saying the leaks have harmed it.
Mr Snowden faces espionage charges from US authorities over his leaks and has obtained temporary asylum in Russia, where he has said he has been vindicated by the public reaction to the disclosures.
However, 56 per cent of Americans say the government should prosecute Mr Snowden while 32 per cent did not favour pursuing criminal charges.
In his speech last Friday, Mr Obama said a third party - not the government - should hold vast stores of phone metadata, and that the NSA would need a court order to search the data except in genuine emergencies.
The US President also promised Washington would no longer eavesdrop on the leaders of friendly foreign governments and that a panel of independent lawyers should be allowed to argue in the interest of privacy rights before the secret court that oversees the NSA surveillance.
The poll found 79 per cent of Americans were not worried that Mr Obama's proposed reforms would undercut the government's ability to fight terror groups.
The margin of error for the full survey was plus or minus three percentage points.
