The Virtual Premiere Friday is not free on any site. The $20 tickets (plus fees for a total of $21.96) are available at: https://worrestudiosboxoffice.com/police-state-virtual-premiere-nevada-34393492021.
If you purchase the ticket, be sure to check your email for the countdown to watch the film. Of course, several people can watch the film on that or the other sites if they are able to gather around the same PC.
Another option is for several people to chip in to purchase the DVD at https://shop.salemnow.com/product/police-state/ and watch the film later.
