I’m not saying it is historically accurate, but I would encourage anyone who didn’t experience interactions with law enforcement pre-9/11 (in the US) to watch early seasons of Law & Order.
It is pretty informative, even in the dramatic context of the show, to see police interactions and the respect for / erosion of individual rights when you view the seasons before 9/11/2001 and after 9/11/2001.
Yeah, after the initial shock and horror of seeing the Twin Towers go down was an overwhelming sense of dread in how that was going to justify an aggressive police state.
