Here's Jaden, come to talk to us about fingerprints. Suitably so; you'll notice the one in the background on the book cover:
It’s week 4 of the FBI/TBI joint Citizen Academy
We’ve spend the better part of an hour listening to a
fingerprinting expert tell us about the history and techniques of
fingerprinting. I’d taken pages and pages of notes on arches, tented arches,
loops, and whorls. We learned about latent prints (invisible to the naked eye
and made when someone touches an object and leaves behind secretions like oil
and sweat), patent prints (visible to the naked eye and made when a dirty or
bloody finger touches an object), and impressed prints (visible to the naked
eye and made when a person touches a surface like blood, clay, or wet or
viscous paint). We learned that criminals sometimes burn or sand their
fingertips in the vain hope of obscuring the prints, but that sanded
fingerprints still show their original patterns, and burned fingertips usually
show at least some of the original pattern. We’ve heard about powders and
brushes and the best ways to get a clear print.
Now it’s our turn to try it.
I slide into a chair as the instructor is handing out items
from the plastic tray at the center of table. The woman to my right, an elegant
woman in khaki slacks and a while silk blouse, has a picture frame. I get a
shampoo bottle.
Our instructor shows us the black fingerprint powder, the
brush, the tape, the pristine white card. Our goal is a clean, crisp lift. He
shows us how to dip the brush lightly in the powder and tap off the excess.
Don’t press too hard, he says. Brush it on lightly. If you apply too much
pressure it will smudge.
I focus on the middle of the bottle, the part you’d wrap
your hand around if you were picking it up. I dip the brush. Tap off the
excess. Brush as lightly as I can. Black smudges appear around the circumference
of the bottle. Nothing identifiable, just some blurry oval shapes and a few
black streaks. A few of the ovals show a hint of a pattern. The instructor says
it’s not always effective to try the part people are most likely to grip. Those
tend to get smeared by palm prints and other fingerprints. Too much traffic, in
effect. He points to a place near the bottom of the bottle. “Try here.”
The woman on my right says, “Look, I have one!” I look at
her picture frame. Sure enough, a perfect print with whatever pattern has
emerged on the surface.
I brush on more black dust. No luck. I try a spot near the
screw-on top. More smudges.
The woman on my right has torn off a piece of clear tape and
laid it gently across her print. Lifts it off carefully and places it gently on
her pristine white card. You can see every swoop and whorl. The rest of us
exchange envious glances.
Finally, I find a well-defined oval with a visible
pattern. Huzzah! By now my fingers are smudged with black. I snag a tissue from
the plastic tray and scrub until my fingertips are a dingy gray. The others are
finishing up, so I give up on the tissue and tear off a one-inch length of
tape. I lay it gently over the print, then place it carefully on my clean white
card. The woman next to me holds up her card and beams. Three crisp prints in a
row, their patterns standing out against the white of the card. I steal a
glance at her hands. Her fingertips are pink and clean, her French tips
polished to a sheen.
I look down at my card. A cluster of blurry gray
fingerprints mars the edges of the card, and there’s a smear of gray on each
end of the tape. In the center of the tape is a perfect…smudge.

I've never tried to lift fingerprints. This makes me want to. Or maybe not.
Although I do have my own fingerprint story: a few months back, I needed to renew my green card. So I went to the ICE office and filled out the paperwork and had my picture took, and it was time for fingerprints. Rolling the fingers on an ink pad, rolling the fingers on a tiny plate of glass.
Now, I may be an alien, but I only have ten fingers, just like the rest of you. And it took an hour. Swear to God. And at the end of it, although the tech said she had what she needed and sent me home, I had to come back a month later and do it again, because the original prints weren't good enough. I'm a person without clear fingerprints. Oh, the crimes I could commit!
The really funny thing, though? The reason why... is because I type too much. Never thought that would be one of the side-effects of becoming a writer. But apparently all the typing is wearing down my prints. There's a story in that...
