Unless it is an active investigation yes they are subject to FOIA. Sometimes all it takes is a simple letter but you do have to be specific on the information you want. Also you maybe charged copying fees. A phone call to the police on their non emergency number you can ask them if they have a special form you may find that they can be very helpful. There are other restrictions that they may place on the information you request if it involves a juvenile the name maybe block out also personal action maybe restricted. other than that I can not think of any thing else. Also you may check on line as a lot of information is out there on the web.
