Authority Shutdown?

Pr. Georges County council passed an emergency bill tuesday that will allow police and other authories the right to shut down dance halls and nigt clubs. If is a threat to public safety. These night clubs and dance halls are located in black areas of Prince George's County. This law is supposed to help eliminate and bring crime down in the community. But if authorities have the right to shut night clubs and dance halls down, how can owner's maintain their profits? If people are attending and paying to come and enjoy their time,when authories shut down those people may want their money back. Being that the location is in a black area, riots,fights, or anything else may happen. So does this new bill make things better or worse?
