should everyones dna be in the data base?

i think that every should have their DNA in the data base just because that would help us catch criminals a lot faster and then the crime rate would would go down also. with having your DNA in the data base i feel that it wont hurt and nor interfere with any freedom because its just in there for the greater good and not bad because its not like the government is going to be looking to see and find every little thing there is to know about u the majority of it would just to help solve crimes a lot faster and put criminals behind bars were they belong.
