U.S. government agencies are properly regulated. Although scandals may sometime occur within a government agency, most government agencies have an internal affairs division which monitors the activities of an agency's members and punishes members who act unlawfully or against the rules of the agency. Government agencies can also be monitored by a third party and be either punished or left alone if they are found to be within the limits of their duties or not.
After last year's exposure and controversy of the National Security Agency's actions, it has become quite clear that such agencies are being unwatched and poorly regulated both internally and externally. Such exposure has led to the public losing confidence that any regulations are being applied and that perhaps other agencies are just as poorly regulated.
Regardless of the agency, there is overspending. The common practice in every government agency is to spend every dime allocated in order to claim more funding the following year. This disregards actual need. Things are purchased that are unnecessary during the end of the fiscal year just to spend the cash. Fraud waste and abuse are commonplace among government agencies, and need more regulation/oversight.
I think that United States government agencies are not properly regulated. I think that a lot of the government agencies that exist today needs to have stricter regulations placed upon them and be more watched closely. A lot of them seem to operate on levels that are not in the best interest of the people.
