They aren't criminals until they are convicted.
While the officer may have felt there was probable cause for a search, searching portions of their anatomy the suspects would be arrested for exposing in public, in public is over the top.
While I am aware that the officer regards the glove as being for her protection, and not the suspects', the possibility of transferring STDs exists, the glove(s) should have been replaced before the second search.
Possession is a crime. Sorry, criminals.
Yes, hubby once came unglued at a veterinarian that used the same glove to examine more than one horse’s mouth. Transference of germs and other interesting things.
I think if the officers thought they needed to do a body cavity search they should have detained the women and taken them to a facility to do that.
