Since the graffiti mentions stuff like "BRING BACK THE PURGE" and "TAKE DOWN PRESIDENT ROAN", yet the theater itself says "Closed for the Purge", that could only mean that some areas still allow the Purge in protest against President Roan after the events of Election Year. I like it. It's like HHN Hollywood has its own Purge Universe (kinda like how California Adventure is going to have its own Marvel Universe).
