Moreover, every major media organization has a conflict of interest on reporting on anyone who controls a substantive portion of their revenue, like any major advertiser in the US. News media thrive on feeding frenzies, because they tend to reduce production costs while simultaneously building an audience interested in the latest development in a particular story. It takes a long time for a reporter to learn enough to write intelligently about a specific issue. Once a reporter has achieved that level of knowledge, it is easier to write subsequent stories. However, major advertisers have been known to spend their advertising budgets through different channels when they dislike the editorial policies. Therefore, a media feeding frenzy focusing on an issue of concern to an advertiser may reduce revenue and profits. Sacco described how "competing news organizations responded to each other's coverage [while] the police, in their role as gatekeepers of crime news, reacted to the increased media interest by making available more stories that reflected and reinforced" a particular theme. "[T]he dynamics of competitive journalism created a media feeding frenzy that found news workers 'snatching at shocking numbers' and 'smothering reports of stable or decreasing use under more ominous headlines.'" The reasons cited above for increased incarcerations (US racial demographics, Increased sentencing laws, and Drug sentencing laws) have been described as consequences of the shift in editorial policies of the mainstream media. Additionally, media coverage has been proven to have a profound impact on criminal sentencing. Prison systems In the United States, criminal law is a concurrent power. Individuals who violate state laws and/or territorial laws generally are placed in state or territorial prisons, while those who violate United States federal law are generally placed in federal prisons operated by the Federal Bureau of Prisons (BOP), an agency of the United States Department of Justice (USDOJ). The BOP also houses adult felons convicted of violating District of Columbia laws due to the National Capital Revitalization and Self-Government Improvement Act of 1997. As of 2004, state prisons proportionately house more violent felons, so state prisons in general gained a more negative reputation compared to federal prisons. In 2016, almost 90% of prisoners were in state prisons; 10% were in federal prisons. At sentencing in federal court, judges use a point system to determine which inmate goes into which housing branch. This helps federal law employees to determine who goes to which facility
