were any problems enforcing the laws and regulations of the new country despite a popular revolution?
For example was there an overabundance of legal hiccups/court cases debating the meaning of new laws? Were there many people who took advantage of the fledgling government, and alternatively was there heavy extortion by what I imagine at the time must have been a improvise/militarized police force?
There really were no law enforcement agencies for the federal government. Remember in 1788 state governments ruled and the federal government was extremely weak. 90% of federal revenue came from tariffs so customs officers enforced that. You did have the Whiskey Rebellion in the late 18th century which was put down by the Army
