Did you read the article? On at least some of the occasions she was volunteer coaching, she gave up her lunch break to do it. She was working. I doubt this is something she would do without the full support of her department administration, and in my opinion, good for them.
For those who think it "inappropriate" for an armed, uniformed law enforcement officer to coach, why? I think I understand why this rule exists (existed) in general, these organizations don't want just anyone showing up to coach armed. Okay. But I'm not sure that was written with uniformed law enforcement officers in mind. With all the school shootings, church shootings, mall shootings, etc. nowadays, you're seriously more concerned about a volunteer coach of 1st through 5th graders in full LE uniform being the armed one? With all that's going on in the world today, some of you are going to ask/demand a law enforcement officer in full uniform disarm because of a rule? Or because you perceive his/her being in uniform to challenge your authority? Good lord. Perhaps if others would be more willing to step up and volunteer, officers in full uniform wouldn't have to. Perhaps consider they're filling roles others aren't, or won't. Reading the article, it seemed the players and most of the parents from her team seem to like her and it didn't bother them how she was dressed. So you toss them from the game site because they won't (or as has been pointed out, can't) comply with your demand. Then you get what happened here, two teams that can't play a game. But hey, at least there's no guns at the field (that you know of).
