Life of Crime (1970)

Siblings, Rachel and Dakota, who both lost their parents in a shoot/don't shoot situation when they were young, set out to seek justice for their perceived injustice of their parent's death at the hands of law enforcement. Their plan works out perfectly until one of the siblings get wounded and they must make the decision, to either carry on with their death-wish or to seek a way out through the Negotiator who is nervously doing his best to get through his very first crisis negotiation.
