Mr. Mohler said the law is useful in cases like those of the 15 police officers because it enabled the county to fill jobs at a lower cost than it could have otherwise. But that does not apply to Messrs. Kamenetz, Gardina, Moxley and Jablon. Mr. Moxley, the assistant county attorney for government affairs, makes $98,500. Mr. Gardina, who is director of the Department of Environmental Protection and Resource Management, is paid $147,900. Mr. Kamenetz makes $150,000 a year, and Mr. Jablon makes $180,000.
