If you have nothing to hide
Those words are the bane of my existance.
Mine too. In other words, your privacy rights don't matter "if you're not hiding anything...right?" Who cares if the Canadian Charter protects us from unreasonable search and seizure, right?
On a related note, a few years back I was camping with a friend in a wall tent in northeastern BC. Deer hunting. 9:00 at night, a vehicle drives across the farmers field we were camping on. Yup, the C.O.'s. Keep in mind it has been dark for 4 hours.
They swung open the tent door and said hi, then asked if they could see our licenses. My friend started to grab his jacket to get his, when I stopped him and asked, "Why? Are we hunting right now?" To which they said, "Well no". You know where I'm going. I told them that since we weren't hunting and were in fact in our residence for the evening, I didn't understand how they could come in and ask for a hunting license. In fact I didn't understand why they had entered private property (the farmer's field AND the tent) without permission; they hadn't seen the commission of an offense so they had no legal right to do that, right? How is this any different than their knocking on the door of someone's home and asking for a hunting license? They didn't have an answer for that.
They let it drop, to their credit, and we had a friendly conversation. I asked if they wanted to share a "beverage" with us.

They laughed and declined, wished us a good night, and left without our licenses being mentioned again.
I'm all for supporting law enforcement personnel, but sometimes they overstep their authority. I don't think it's a bad thing to politely and respectfully remind them of that when it happens.
