Picture a proud African American police officer from the Colorado Springs force on the phone with David Duke, convincing him to send him this KKK card.

Yes, it really happened. And under the direction of Spike Lee from his screenplay with Charlie Wachtel, David Rabinowitz and Kevin Willmott from the book by that policeman, the story of how Ron Stallworth thwarted some really bad things with his undercover work in the early 1970s.

In BlackKlansman we get to see Stallworth use his wily ways, silver tongue and a handful of sympathetic colleagues to infiltrate the local chapter of the KKK and keep them from killing a visiting pioneer of the Black Power movement.

Lee’s film captures the hate of the old guard and the passion of new players in the city, too, as oil and water mix with a lot of the expected results. There’s enough bad behavior by the supremacists to keep a viewer good and mad and enough smart work by Stallworth to keep you rooting for a good ending.

Stallworth convinces Duke of certain things on the phone, 100 percent so. Bravo!

His detective work allows the right people to come out on top.

Damn, John David Washington is great as Stallworth, and Adam Driver stands out as his No. 1 partner, and Topher Grace creeps out sufficiently as David Duke.

You better believe it. (From IMDb.com)

Yes, I cheered the victories by Stallworth and his crew.

Then the credits roll, and Lee has positioned clips from some not-too-distant history to keep anybody from gloating.

The battle is still raging, indeed.
