In the first scene at the Barton ranch, Lucas is shown getting out of an entirely different car than the one he drove onto the ranch.
The used car that Lucas buys at the car dealer is medium-colored. Yet the car that "he" drives (is driven) to the farm (wide shot) is black. A moment later, the car that Lucas arrives in at the farmhouse is back to being medium-colored.
Also, the driver of the black car is not Lucas; the driver is wearing a different shirt, with a neck tie. (Lucas arrives in a checkered shirt and a bow tie.)
Because of "reused footage," the driver of the black Chevrolet is actually actor Parley Baer from "Bouncing Boomerang" (S7/E11).

The murder victim drinks poisoned lemonade, collapses immediately, and dies aboard an ambulance. The poison was mercuric chloride, which, like all metallic poisons, is rather slow-acting.
When Perry and Lucas are talking after the courtroom revelation about Lucas's first wife, Lucas takes his "home remedy" pill to ease his liver problem. It is unlikely that he would have been allowed to keep such an item while in custody on trial for murder.
A sign at the entrance to the used car dealer's lot reads, "Your Credits Good Here". It should be, "Your credit's good here".
