I work on no classified systems, data, or anything else. Yet, my job requires me to have a security clearance. Which is another huge waste of taxpayer cabbage to the tune of several thousand dollars. And then they still give out security clearances to people like Bradley Manning who throws a temper tantrum because he's gay and picked on in the military so he downloads the entire SIPRNet and gives it to a bunch of American-hating douches.
So what is the answer? Well, use it or lose it. The program managers and civilian leadership need to pony up about security clearances. If their charges did not use their security clearance in the entire space it was active before the renewal date comes up, then don't renew it. Take the job off the list for clearance required. Then give more time to investigate the Bradley Mannings of the country.
