The Purge movies are horriblly irresponsible, especially with global and national situations. Hollywood is more concerned about showing someone smoking tobacco (marijuana's fine) than about showing the slaughter of humans.
The Purge movies also don’t factor in rednecks and war veterans. I can start my own purge with my Remington 870P, M4, 1911, or .357. All kinds of tools to chose from.
