Better lit streets are almost always viewed as safer, and for good reason: less crime occurs in better lit areas. Following that logic, installing lights in order to prevent crime is an eminently logical move by police, and something that can easily be implemented elsewhere is a positive effect is seen.
Yes! I think the Crimefighter lights in Chicago were a brilliant idea and I'm glad they are being implemented. More cities should install Crimefighter lights in their cities as well because I do believe that it lowers crime rate slightly. Especially because not many people are going to commit crime when it is bright outside.
