>>115590852Anon, The reason why those cases take 30 years to solve is that only in the year the criminal rapist was arrested on another charge, was his dna filed into the database. The database was then checked to see if it matches any unsolved case. This is usually done regionally by city to city case by case basis. So even then sometimes the rapist escapses the system if he jumped to say another state.
So their a ways to fix it but they're either messing with civil rights like harvesting everyones dna and then putting it on record, or because it infringes on state rights.
As for technology, we've put millions in Nasa, how close do you think we are to traveling to mars? These things take time. Usually by lets say 30 years.
