Houston Expands Downtown Surveillance, Unsure If It Helps

SpaceGhost writes "The Associated Press reports that the Houston (Texas) Police will be adding 180 surveillance cameras in the downtown area, bringing the total to close to 1000. While most cover public areas (stadiums, theater district) the police suggest that Houston also has more 'critical infrastructure' (energy companies) than other cities. Interestingly AP points out that 'Officials say data is not kept to determine if the cameras are driving down crime.' Didn't London face the same issue?"
