Chicago Mayor Rahm Emanuel wants more security cameras downtown. At a meeting of the Public Building Commission, members approved a measure adding cameras.

The American Civil Liberties Union has long said Chicagoans are some of the most video-taped people in the country. Adam Schwartz, an attorney with the ACLU, said he’s not opposed to increasing security at those buildings, but having too many cameras around the city is a privacy concern.

“What we think is that the cameras should not be going up everywhere; that there might be some particular locations where the cameras are more appropriate,” he said.

The ACLU estimates there are 10,000 cameras around Chicago.

A spokesman for the Board of Trade said it supports the mayor’s efforts to increase safety in the city.
