Any type of glove is dangerous. It leads to false confidence. Gloves can leave distinctive fiber and impression evidence on their own – independent of fingerprints.
Gloves must be disposed of carefully. Destroyed if possible, then scattered. If they come from a big box with many gloves, the entire box must be disposed of. Investigators can check if a glove came from a particular lot.
Gloves might leave fiber or impression on his car’s steering wheel.
From an ident site:
“Please wear gloves when processing latent print evidence, with frequent glove change. Prolonged glove use may cause sweaty hands, which can result in leaving YOUR latent print through a latex glove.”
