Government workers drug testing

believe any and all government and state workers should pay to be drug tested weekly why because there's so many of them that's doing illegal drugs and getting away with it for instance I know of a individual who works for child protective services and sales illegal drugs but families get torn apart just for that government worker go do same criminal activities there's a man that is part of the district attorney office and he drives around asking homeless men for pictures of there private parts pays them 20$ each time these people have be treated as any person who wasn't a government are state worker and having them pay for there own weekly drug test is a start.
