Is a cop allowed to have a piercing?

Answer 1

It depends on the company the cop is working for. Some companies let employees have tattoos but no piercings and vise versa. Most police departments do not allow piercings with things in them while on duty. Some may have regulations about them off duty as well.

Answer 2

Yes, although a law enforcement agency may have rules on what jewelry may be worn while on duty. Generally, male officers may not wear earrings or similar jewelry while in uniform, and female officers may wear only small ear studs or loops.
