Is the movie american hustle too vulgar?

In 1970s, the FBI conducted an investigation in Harpark and Long Island, new york, which was later called "Albers Cam". The FBI originally intended to investigate the theft, but unexpectedly found many illegal official corruption from the case. After a series of investigations, a senator, six representatives, a member of New Jersey, a member of Philadelphia City Council and an immigration official were finally convicted. The case caused a great sensation at that time, not only because so many elected officials were corrupt for the first time in American history, but also because the FBI used bottomless undercover agents in the investigation and did a lot of fishing law enforcement acts. Under the pressure of public opinion, after the judicial procedure of the case was completed, BenjaminCiviletti, then the US Attorney General, issued the "Guidelines of the US Department of Justice on the Undercover Action of the FBI" specifically for such cases, clearly stipulating the judicial rules and procedures that FBI agents should follow when conducting undercover investigations. According to this story, director David O 'Russell adapted a new film "american hustle", which was officially released in the Christmas movie market in North America in 20 13.
