Other mistake: At an RV park, Hank is investigating an RV that looks like the one he saw in the pictures from the ATM camera. Desperate for a vantage point, he goes around to the back of the RV and starts to climb up the ladder on the passenger rear side of the vehicle. This RV is not supported at this time in a permanent fixture, as it's revealed shortly there after that the occupants were just on vacation. So Hank's full body weight getting on the back corner of the RV should have shifted it on it's suspension and alerted the people inside that something was going on far sooner than it did.
Other mistake: Gus is talking to his employee about the twins while writing something on a clipboard. However, he is using the opposite end of the pen and just pretending to write. (00:14:40)
Continuity mistake: When Walt asks for the RV to be destroyed, there is tape over the bullet holes on both the inside and the outside of the door. However, when Hank is showing the bullet holes to the owner of the lot, he takes the tape off the outside and the light shines on Walt. No-one has touched the tape on the inside. (00:28:50 - 00:36:00)
Visible crew/equipment: During the shot from the interior of the car of Hank following Jesse, a camera man in a green T-shirt can be seen crouching down on the road to the right of the screen. (00:30:40)
Continuity mistake: Walt asks Gale to recite the poem he mentions, which Gale does, reluctantly. When he starts the first line, the camera is behind him and he lifts his head to look up at Walt straight in the eyes. When the camera cuts back to a shot of his face, he's suddenly looking down again.

Chosen answer: It is part of the ritual for la Santa Muerte. It is a sign of humility and sacrifice.
