    if (inicio != crime.getStart() && fim != crime.getEnd()) {
    
        return  (crime.getEnd() - crime.getStart()); }
        
    if (inicio > crime.getStart() && fim < crime.getEnd()) {
        return  (crime.getEnd() - crime.getStart());

     return (crime.getEnd() - crime.getStart());   
}
