South Carolina woman accused of using ambulance as taxi -- at least 100 times | Fox News: "A South Carolina woman was arrested after authorities discovered she called 911 at least 100 times in the past seven years to get rides into Charleston, the Dorchester County Sheriff's Office says.

Audrey Ferguson, 51, allegedly faked illnesses and would immediately sign out of area hospitals upon arrival, telling doctors she was fine, WCSC reports."

"Each of Ferguson’s trips cost $425 plus mileage, and officials say taxpayers may have to pay a bill of more than $400,000 to cover expenses that aren’t covered by Medicaid, WCSC reports."

The False Security of Surveillance Cameras | Cato Institute: "Between the throngs of spectators and police on the scene and the television cameras broadcasting the event, the Boston Marathon must have been one of the most monitored spots in the country on that grim afternoon.

That we can identify suspects from video footage after the fact — knowing the time, location and method of the attack — does not make it realistic to suppose an observer at a monitor station could have identified the impending attack and intervened in time when those on the ground did not, however comforting that supposition might be.

Terror attacks are (thankfully) so rare and varied that any system with the slightest chance of detecting a real one would necessarily yield a vast, paralyzing number of false positives.

It is also unlikely that cameras will be especially helpful in deterring such attacks. Even when it comes to ordinary crime — where the perpetrators are generally motivated by the desire to make a quick buck without getting caught — studies have been mixed and inconclusive about the value of CCTV cameras as a crime deterrent."
