Chicago Police on patrol or rolling to a crime scene will no longer be allowed to do so with visible tattoos, baseball-style hats and other points of personal appearance previously allowed, according to a revised uniform code.

161 murders in 151 days

On Monday, the Chicago Police Department put forth a revised uniform code that’s sure to get some officers hot under the collar . . . or long sleeves and pants, as the case may be.

“Members with tattoos or body brandings on their hands, face, neck, or other area not covered by a long-sleeve shirt, long pants, or appropriate attire will cover them with a matching skin tone adhesive bandage or tattoo cover up tape.”

On Tuesday, the Fraternal Order of Police vowed to fight the mandate, calling the dress code a “mandatory subject of bargaining,” according a communication sent to members by union president Dean C. Angelo.

The department, in a statement, said the uniform code revisions were made to make officers more immediately identifiable “to promote uniformity and professionalism. Too many uniform variations became available, making Chicago police officers less immediately identifiable to the public.”

Here’s the full 28 pages of rules and regulations, which go into effect on Friday and are supposed to be enforced by supervisors:
