I'm currently watching "la Casa de Papel" a.k.a. "Money Heist", which is a series taking place in a hostage situation. There are a lot of things happening, of course, but there were two incidents that raised some "legal" questions in me.
Sorry, there may be spoilers. Also, I am not a law person so my wording might not be correct.
Incident one:
Hostage A is trying to secretly steal a weapon from the heist men, hostage B (which happens to be an employee of A) sees him and then A is threatening him that if he says anything he will fire him after the heist.
Incident two:
Hostage A and three of the heist men (after a failed escape attempt) are pointing guns at each other, Hostage A threatens them to open the door, the Heist men try to convince him to put the gun down, then, Hostage C disables Hostage A.
Since the heist is under police handling, could anything you do inside the heist considered as interference with the police work? e.g. if the behavior of Hostage A causes a shooting that results in people getting killed - but not by Hostage A. Will Hostage A then be responsible for those deaths since he interfered with police work?
If yes, are the Hostages B and C justified for their behavior for trying to stop Hostage A?
Since the country may matter, just for the sake of it, let's assume that the events take place in Spain.
