On the flip side of this...while Kansas does not currently have any law in place saying one has to identify himself to an officer at any time, persons who are driving ARE required to identify themselves and to prove they have a valid driver's license. Most people do this by carrying their driver's license with them and show the officers as identification. However, from my experience, about 50% of people seem to not know where their license is or else intentionally did not carry it with them when they left their house. For instance, if I got pulled over and knew I had a warrant or was wanted or just did not have a DL, I could give the officer my brother's name and date of birth. I know he is not wanted and he does have a valid license. By asking for fingerprints of someone who cannot identify themselves by having their valid DL in possession, the process will identify them IF their prints are already on file.
In good ole
DC, we do have a problem with people driving without a license and not having any ID at all when they get pulled over. And believe it or not, a lot of people in
DC have two or more names they use as their real name, their work name, their hyphenated name, etc. If a person is pulled over and has no ID, and gives the name John Smith with a DOB of June 22, 1973 - a quick field check of prints might save a lot of time by instantly identifying this person as using the John Smith as an alias and be able to give their real name. I can see where this would be very useful and would like to try it myself on traffic stops - but only when the driver has no ID.
