We have a huge backlog of DNA evidence that has yet to be tested, analyzed and cataloged, because there is a shortage of laboratories and technicians - because it is not being adequately funded.
We could use another 50 labs in this country, as well as better computer systems and better networks to link our various LEAs and the various levels.
But that kind of spending is dull, boring, doesn't make police unions or police officers themselves all that happy. Whereas many of the beneficiaries of the weapons systems type of spending find the whole process rather fun and exciting.
