A memorandum issued by the National Capital Region Police Office (NCRPO) reminds officers not to do anything that might create a negative impression among members of the public, the Philippine Star reports . As well as leaving their noses alone, officers in the capital, Manila, have been told not to play online games, smoke or chew gum during their shifts. The list also specifies that any bodily itches must remain unscratched, and officers should avoid "unseemly posture" such as standing on one leg, the paper says.
