From the Lawrence Daily Journal-World for Sept. 19, 1971:

A change was taking place at Lawrence police headquarters. The department’s policies had been altered on Sept. 1 to allow officers to wear mustaches. “Full” haircuts were also permitted, but hair was still to be trimmed so that it did not fall into the eyes or meet the collar of the uniform shirt. The policy change had resulted from an officer having been suspended without pay in August after having disobeyed an order to shave off his mustache. The suspended officer had been reinstated the day after an article had appeared in the Journal-World about the suspension, and after consulting with City Manager Buford Watson, Police Chief Richard Stanwix had ordered the change in policy.
