The presentation of the data does not support that analysis.
We have
Total 12,658
Felony type total: 2,137
Suspected felony type 64
Other than felony type total: 6,678
Unknown 3,779
One notices that the four subtypes listed add up to the total. One also
notes that there is clearly a catagory for suspected felony type, so it does
not seem reasonable to assume that the FBI meant Unknown to be taken as
suspected felony.
In general, the catagories are
A
Suspected A
~A
Unknown.
It is clear to me that unknown means unknown. There is no reason to assume
that, simply because something is not under ~A that it must be A. Unknown
is a very critical catagory in any data analysis of this type.
