Three Billboards Outside Ebbing, Missouri2017

Willoughby:
I'd do anything to catch the guy who did it, Mrs. Hayes, but when the DNA don't match no one who's ever been arrested, and when the DNA don't match any other crime nationwide, and there wasn't a single eyewitness from the time she left your house to the time we found her, well... right now there ain't too much more we could do.

Mildred Hayes:
You could pull blood from every man and boy in this town over the age of 8.

Willoughby:
There's civil rights laws prevents that, Mrs. Hayes, and what if he was just passing through town?

Mildred Hayes:
Pull blood from every man in the country.

Willoughby:
And what if he was just passing through the country?

Mildred Hayes:
If it was me, I'd start up a database, every male baby was born, stick 'em on it, and as soon as he done something wrong, cross reference it, make 100% certain it was a correct match, then kill him.

Willoughby:
Yeah well, there's definitely civil rights laws that prevents that.
