I used to believe the same as several others; I've done nothing illegal, I'm doing nothing illegal, therefore search away.
In light of events of recent years, I now feel differently. If they want to search my rig, a warrant will be required. If I have to sit there a while, so be it. I will not freely give up my constitutional rights. I have several LEO friends, and they actually agree with me.
Here's the thing; Yes, most cops are good folks...however, it just takes that one cop to possibly ruin your life. Example; When you travel, do you keep ALL of your medicines in the container they were purchased in? Or do you use one of these plastic walmart containers where you divvy out your meds for each day? "IF" you have pills...(could be an aspirin, or hydrocodone) that are not in the original container and clearly marked with your name, then you have broken the law in most states, and they can prosecute you accordingly. Yes, you can probably get out of trouble by producing said prescription or original container, but your vacation will be ruined and your life will be a mess for weeks or months. And the cost will be high. lawyers are running around $250 an hour these days...some are higher.
Nope, no searches of my stuff without that warrant.
Having said that, I will be as cordial and pleasant as possible. I will not behave antagonisticly or confrontational at all. I will politely identify myself, show them my drivers license along with my CHP, and inform the officer where the firearm is located. But I will politely decline to answer almost anything else. My business is none of his business. Making small talk can get you in trouble as well. I might discuss the weather, but little else.
I will try to politely maintain control of the conversation by asking him how his day is going. How does he like the vehicle he's driving. Has there been many wrecks on this stretch of highway....etc... there's no end of questions I can think of .
Anything else is up to him or her.
Having said that, I understand that they can bring the dog in, and the dogs handler can get the dog to bark at the right time and right place giving them probable cause. If they really want to search, they will....no matter what i think. They will still have to go through the right steps. That dog might be hours away, and this officer would also be just hanging out until the dog was on site..... Might be more inconvenience for him than me....I can always go inside the coach and make a sandwich....
my 2 pennies....
