You can do many things with numbers that are not valid. There is no real world meaning to the arithmetic you are performing. The relevant question is the accuracy of the FBI's crime count which can only validly measured against total crimes.Percent of increase.
the 6.6 is divided into the -2.1 to get 3.142857142857143
times by 100 you get the percentage 314.2857142857143
If the temperature went from 10 degrees C yesterday to 20 degrees C today, it would be meaningless to say the temperatures doubled. If would meaningful to say temperatures went up by 10C (18F).
