The blood splatter on the truck changes size and shape between shots.

When Walt and Jesse get into an argument at Jesse's house, Jesse throws the GPS tracker at Walt's head. It's thrown on the left side of his head, but in the next shot, Walt is bleeding on the right, front side of his head.

When Hank checks the GPS, Google Maps copyright is from 2010 but the scene takes place in 2009.

In the fight scene between Walt and Jesse at Jesse's house, the items on the table move inconsistently between shots.

Hank is singing just as Walt is turning into the restaurant but at 2:26 the camera angle shows Hank from behind not singing but one can still hear him singing.

IRS Criminal Investigation does not issue summons, but instead issue subpoenas. Summons are issued by the civil side, which are Revenue Agents, not Special Agents.

For the size of the scope on the sniper's rifle and the distance he is away, with the bullet hitting over a second before the gunshot is heard, Gus's face wouldn't take up six mil-dots as seen from the sniper's position. Centered on the cross hairs, it wouldn't even touch one mil-dot on either side.

The sniper is on Jesse's right as evidenced by the direction of the injury/blood splatter from his co-worker, but then in another shot the sniper is in front of Jesse. However, there's more than one sniper.

During the fight between Walt and Jesse, Walt throws Jesse to the floor and then kicks him in the face. You can easily see that the kick does not hit Jesse.
