Cleanliness next to Godliness
I saw a new officer do this the other day. After he took a prisoner to jail and the cuffs were removed, he just placed them back into their holder on his belt. Being new, I felt I had to caution him about that. I thought I'd pass along this same tip to PoliceOne members.
When possible, always wear gloves when handling a prisoner. Also always disinfect anything that touched the prisoner.
