Do gloves leave fingerprints?
Wearing gloves in almost all instances would prevent a fingerprint being deposited on the surface, but research has proved that thinner gloves, mostly latex gloves, would still leave a fingerprint, through the glove, on most surfaces. Prints left in that way can still be developed and used for identification.
