People can think what they wish.
You're not telling them you're a cop. You dont claim to be a cop. You are asking them a question; If I was in uniform, would you still be worried?
common sense says nothing bad will happen
Just like putting a light bar on your car and flashing it behind motorists isn't telling them you're a cop...
It also entirely defeats the purpose of OC for advocacy, but more importantly panders to the notion among many Americans that only LEOs have the right to protect themselves. Attempting to commit a crime (impersonating an LEO) in order to dilute a constitutional as well as human right seems so wrong to me on so many levels.
It's funny how you bring up "lightbar on your car".. Funny because I had a TomarLED lightbar on the roof of my durango. For many of the police stations out in Jersey I would be of assistance and help direct traffic. I was able to do this being I was an explorer. My LED lightbar as many of you know, are white/clear in color, and when on, was all orange in color.and it was nice to drive down the highway, or on city streets in my silver durango and many people would get out of my way (not because I had the lightbar on,but because it was a durango, common police suv in Jersey. and there was a lightbar on the roof, which if I look in my rearview, and I see a lightbar like that, I just move to the next lane, I'm not going to chance if it's an officer or not). Yeah they THOUGHT I was a cop, but wasn't. You can't control what people think. But I guess at the time I should have been thrown in jail for having a lightbar on my truck, because people THOUGHT I was a cop.. I can see how that is also impersonating an officer being it is a newer version lighbar made/designed without colored lenses.
I also had two strobes in my headlights, and two strobes in each tail light, which I never used unless required to in order to direct traffic or if in route to a fire call
I stand by my case, you can't change what people think. You can control what they think. If you went to court, you'd come out free if someone wasted their time to take you in for impersonting an officer based on the question "if I was in uniform, would you be worried?". That question doesn't contain cop, officer, trooper, law, enforcment, security, or any other possible words in order to make that question, turn into a felony charge.
