The purge is basically a 12 hour period of, fuck everything nigga who gives a fuck.
Couldn't have said it any better lol.. Otherwise, it's a possibility that something similar to the Purge will be allowed in the US. It'll probably will only happen if we have such a strong police task force where crime is super low with higher end punishments, basically forcing people to be 'good' until the Purge will let them release pent up frustration and anger upon people. Highly unlikely though.
