I think people against this would think cops will start using this to catalog people. I guess maryland can afford this but I would think this is expensive as fukk to get some one's dna unless they would save the swab until they use it. either way even in there statement they are using it to id people and since fingerprints do the same thing and are cheaper to produce i think alot of other states would stick to taking your fingerprints.
fingerprints really used to suck. shyt was mad tedious how they would press and roll each finger. last time I was in there shyt was all digital though
I'm not sure about the methods for dna collection. I would imagine the best thing would be to analyze it right away, and just store the data. but i imagine they have to 'send it out' to a lab and shyt. it does say that it would only be for "charges relating to a serious offense"
