I have heard several stories where officers were off-duty and got pegged as cops by some heathen that had an axe to grind with them. Thugs are thugs, and they may be waiting for an opportune time to get even. The good guys may have not have been prepared for the attack. What is more disconcerting to me is if you are accompanied by family or civilian pals when such an incident occurs. But that's a topic for another column.
Perform a fashion check before you leave the house: Do I look like a cop? If so, then go prepared. If you don't want to be bothered, tone down the wardrobe.
Watch Your Mouth
Watch your mouth in casual conversations. I know that if we are in a public place there is not a real expectation of privacy. Let's say I am visiting your fair city and you want to take the old chief out for a beverage. Others (both good and bad) could be listening to our casual conversations.
Cops are the only folks I know who have to talk in signals, codes, and use terms like EPD and, my favorite term, perpetrator. It doesn't take a stellar person to deduce that people using this lingo, even in civilian clothes, are cops having an afternoon off for some cool-down time. Watch your mouth and terms; it will keep you out of a tiff.
