According to an amNY exclusive, surveillance cameras of one form or another have been very effective at capturing crimes in progress, boasting a 45% success rate for offenses committed in the first four months of 2011. However, the devil is in the details: “It’s unclear, though, how often the video leads to an arrest.”

But hey at least it’s great content for news outlets! Despite their inability to prevent crime, which is how these things are sold in, the City is still moving ahead with plans to use federal grants to install a “$201 million network of 3,000 public- and private-sector cameras in Lower Manhattan and midtown by 2013.” Well, that should certainly make everyone a lot safer than cumbersome old firehouses.
