AMERICAN RACEWhen it comes to race relations in this country, who’d you rather turn to than Charles Barkley? Well, maybe a lot of people. But the NBA star and analyst hosts the two night “American Race” (TNT, 9 p.m.), in which he travels the country to take the pulse of its people. IT begins in Baltimore, two years after the death of Freddie Gray ignited the city.

A second hour at 10 takes Barkley to Texas, where Muslims struggle among local laws and protests. The final two episodes air Friday.

Barkley seems genuinely interested in his topic, and his celebrity brings him access. Most important, a lot of different voices get to express themselves.
