during the discussion about how much money is needed to cause a real ruckus in four states, one of the students or whatever they are empties his pockets, holds up what he finds and jokes "I got a phone card, some condoms and a battery, if that's any help".
These individuals appear to be involved in the attempted uprising (however delusional), and they appear to be running low on funds. In the second part of the clip, money is still on their minds. This time they more or less jokingly demand it from the man behind the camera.
I think this clip was shown to demonstrate what these types are all about. Cheap little thugs looking for a handout to pay their way through fighting the "revolution". The video also establishes that they appear to be trusting the American, and suggests that some money may indeed have changed hands between them.
The other clip is not at all without context, and it's not an interview. Antonio Rivera is directly addressing one of the young pro-Capriles protesters, explaining what they can and should do: "You can throw stones, you can throw bottles" (he doesn't go into such details as to whether these bottles should be filled with incendiary liquids first etc.), but "you must stay together and not let them disperse you" and "it is important that everything you do stays within the directions given by Capriles". The man behind the camera is apparently a person of trust who can hear and record this.
Es importante mantener todo lo que hagan bajo la direccionalidad que tiene Capriles
