why and what purpose are they for and does any one have any pics of them and what are reasons for making them was it in drug infested areas ? or something

i guess since a crimefighter has a verticle lamp and a bucket refractor it has the ability to light large areas and in theroy lighting at night reduces crime but most crimes appear during daylight hours so they obviously have the purpose of lighting the streets what i do not know is why they have such a strange optical assembly.

They are designed to illuminate 360' making it brighter all around. A conventional streelight mainly illuminates a long narrow strip with less light toward 'house side' and 'street side'.
There isn't too many pics, this  is one I found.

it seems crimefighters are just ge cobraheads with modified optical assemblies.

but why are they usually only found in the chicago area?

Form109: I think Chicago had problems with crimes a few years ago.

well several places in america suffer a relative high crime rate.

some examples would be.

new orleans

houston

chicago

atlanta

washington dc

compton

dallas

crime can occur anywhere but most often appears in large cities.
