That it is not accurate for you is half of the point. The people / processes that rely on that data will insist that it is perfect.
I can call the police and fabricate an accusation of rape against you. With any form of evidence, they can and will arrest you. When my rouse is discovered, the charges will be dismissed immediately, and I'll be in trouble, blah blah blah... but meanwhile, YOUR arrest record will be entered into the local and national databases as a felony/sex/violent crime.
And for the rest of your life, you will be subject to Felony Stop procedures any time a cop pulls you over.
See the problem? Database isn't accurate, but every player involved on that database-side has no incentive to challenge it. The cops on the beat will want to know you're a probable felon, right? Who's going to be dumb enough to remove that data record?
Even better, since you'd now be tagged as a not-yet-convicted sex offender, and nobody is going to remove *that* record, either. The database... is perfect.
