And what's the alternative? Is it worth it?
that's what i want to know from these who keep beating this "police state" drum.
I've seen their explanation either. Very easy to play MMQB after an incident. Much harder to talk about what steps the government should take to try and protect the public, both before and during an attack.
Regarding cyber crimes, here is an example of what one little hoax can do:Twitter Hoax Sparks Swift Stock Swoon
By TOM LAURICELLA, CHRISTOPHER S. STEWART and SHIRA OVIDE
A short-lived hoax on Twitter briefly erased $200 billion of value from U.S. stock markets on Tuesday, underscoring the vulnerability of financial markets to computerized trading programs that buy and sell shares without human intervention.
A tweet purportedly from the Associated Press just before 1:08 p.m. reported two explosions in the White House and that President Barack Obama had been injured. The posting sent the Dow Jones Industrial Average tumbling roughly 145 points in an instant.
Minutes later, the AP said the tweet was a fake resulting from hacking by an outside group, and the White House confirmed there were no explosions. But traders employing so-called algorithms that automatically buy and sell shares after scanning news feeds—including posts on social media sites such as those run by Twitter Inc. and Facebook Inc. FB +0.50%—had already taken action.
The two-minute selling spree left many traders stunned and dismayed, even though the market quickly recovered the losses afterward.
"It's frustrating and scary that a tweet can erase hundreds of billions from the market in a short time, but that's the world we live in," said R.J. Grant, associate director of equity trading at Keefe, Bruyette & Woods.
Stocks Notch Strong Finish After Reeling From Fake Tweet
.In a Twitter post, a group identifying itself as the Syrian Electronic Army took responsibility for the fake AP message. The group, which describes itself as "a group of enthusiastic Syrian youths" who support Syrian President Bashar al-Assad, recently has targeted other media organizations. An AP spokesman said the news organization was unable to determine the origin of the hacking incident.
Securities and Exchange Commission officials are looking into trading activity that took place in response to the AP tweet, according to a spokesman, who said the agency routinely looks into irregular market action. Regulators looking into the activity said it was too early to tell if the tweet was intended to disrupt the market. Jenny Shearer, an FBI spokeswoman in Washington, said the bureau is also investigating the incident. She declined to provide further details.
