I found this so you can read about what I am talking about.
In a nutshell. They are trying to get anybody doing anything in the data bank so when those that kill leave DNA it will be an easy trace to the killer.
Killers aren't usually one time offenders. They have history.

Accused Hannah Graham-murderer Jesse Matthew, who was convicted of trespassing in 2010, inspired three bills in the General Assembly to add misdemeanors to the crimes for which DNA samples are collected. However, the versions that passed would not have prevented Matthew from crossing paths with Graham last September.
Had Matthew been buccal swabbed for DNA in 2010 after the trespassing conviction, he would have matched DNA taken from both a brutal 2005 attack in Fairfax and the 2009 murder of Morgan Harrington, and been in jail the night Graham wandered up the Downtown Mall, said proponents of the bills.
Local delegates Rob Bell and David Toscano and Senator Mark Obenshain got bills passed last week that target 13 misdemeanors, most of which involve sex crimes like indecent exposure, attempted rape and peepingbut not trespassing.
Albemarle Sheriff Chip Harding, who pushed to get Virginias DNA databank funded back in the 90s, wants to see DNA samples taken for all Class 1 misdemeanors, which is done in New York. Harding said hes grateful for this first step, and noted that it took New York seven years to get its legislation passed. In particular, he wants trespassing, petit larceny and assault and battery on the list because of the large number of hits connecting those crimes with more serious felonies.
I think its a win, he said of the legislation that next goes to Governor Terry McAuliffes desk. I was hoping for a bigger win. I feel very confident that the next 10 years, well have all Class 1 misdemeanors in the databank.
