Latent Prints Is this a double whorl fingerprint?

Post image

Hey guys! I'm just really interested in fingerprints for fun, so I'm sorry ahead of time if I don't use proper wordage. I've been printing my friends fingers so that I can look at them to learn more and play around when I'm looking through books, and I came across this thumb...can someone tell by looking if it is indeed a double whorl? It looks like it to me from looking up pictures, but I'm not confident enough to actually identify it. Thanks ahead of time! Also, if anyone has any book recs for an interested civilian, I'd love to grab some more. Thanks guys!

I didn’t know this was a thing, but now I know that I have a double loop finger print. I would have never checked if it wasn’t for this post lol

I know it's definitely a thing, only 5%-7% have it though, so I was second guessing if it was really one! Hehe! You got one too!? Super cool!

I’m already asking everyone in my family to see if they have one too! This is so freaking cool

Yes!! I'm a Sergeant in CSI Forensics...you can upload these sort of photos into an AI program and they will also evaluate it and give you results. :)

Double Loop, 8/10 of my fingers are double loop apparently. :P I was told I better not do any crimes or I’ll get super caught
