Why do you think fingerprints are useful to crime scene investigators?

I think my fingerprint is working, my thumb is a loop and it was good to hear that my fingerprint is a loop. It was really good that I see what kind of my fingerprint, I and my group work very will we follow the instruction that gives it to us. It is really hard to follow the interaction because there is too much instruction that they give us, but we still did it.  I think I could do next time is to do it closer,  Lots of people have different fingerprint and not only me, But Lots of people also need fingerprint for some reason we need it. Police have used fingerprint evidence to catch and convict criminals And also fingerprints are useful for investigators to find the criminal easily.
