Coding Challenge #43 String of Crimes

An exercise in recursive objective propagation in a functional paradigm. Really just for some fun in a simulator-type virtual city.

/*crime tree
    each crime can have several others (given a simple crime, we can do other crimes, as long as the victim is alive or the assailant is willing)
    like: criminal X wants to rob someone. this may lead to other crimes like (defendant Y fights back) battery, 2nd degree murder, disposing of a corpse
