Is it working?  Are the rules being followed? Is it worth it? 

While compulsory, independent audits of both program performance and potential policy violations are important, they are less effective if the results are not shared with the public.  Regularly published reports should inform communities as to whether the technologies surveilling them are achieving their public safety purposes and whether policies and civil liberties protections are being followed. Knowing that audit results will be public can provide incentive for government agencies to carefully follow policies and regulations. 

Transparency also helps with the long-term maintenance and evaluation of a surveillance system.  If problems arise, residents and their elected representatives need to be made aware of new threats to public safety or risks to civil liberties so they can quickly and effectively address problems.
