Not the greatest example but I see your intended point. There are several regulations surrounding the manufacture of radar detectors/scrabblers. One of the regulations is that the designers have to hand a beta over to government researchers. Only after the researchers have manufactured a radar/code that can defeat said detector/scrabbler, is the company then allowed to manufacture and market it. So you are not more advanced than the police. Now...that being said, not all jurisdictions can afford the latest and greatest technology...
