The gun violence of Purge caused issues the last two years. Purge was supposed to be a street in 26, but what replaced because of the Pulse mass shooting. It ended up being a street and part of a house in 27 and after the Las Vegas mass shooting, they removed certain gun props on the streets and downplayed them as much as possible in Horrors of Blumhouse.
I don't think they will go that route again, especially with the movie being so politically charged.
