Prax, this varies by agency. I'm willing to bet that when the operator heard "roommate" that the much dreaded "domestic" light flipped on. I've been on more than a few of those, and they range from Mary and John Smith yelling at each other to them shooting at each other. On a domestic call, dispatch either tells that there are weapons at the scene, or the responding officer(s) ask(s) dispatch.
Telekinesis is right. Always be truthful. In a "he said she said" situation, you're success is all about whether or not you are considered to be trustworthy. If you lie and are caught in that lie, you just lost that. Will you "lose" the encounter because of that? maybe. Do you need to take that chance? I wouldn't.
We're not a mandatory disclosure state, but I've had several people hand me their CCW with their driver license. When I see it I know I'm probably not dealing with an international terrorist out for blood. (And no, in Alabama, carry permits are not linked to the driver licence.) I don't care if you have guns in the car. I'm not running the SNs on every gun I find without a reason to. Where I am, I'd do that 24\7 and STILL not get them all run...
zxcvbob - You can ask for a warrant, but you'll be disappointed in how fast that can typically be accomplished. One agency locally has laptops AND cellular fax machines in the cars. The officer detains the subject, then faxes the probable cause affidavit in, is sworn over the phone, and have the warrant faxed back in less than 30 minutes. (This system was set up due to the HIGH level of drug traffic locally.) I'm not saying you don't have the right to demand one, because you do, just don't be surprised when the officer in question doesn't say "Aww shucks!" and walk off and forget the whole thing.
Nice to have my gut feelings confirmed this way. Thanks.
In my opinion, and personal experience via the odd traffic stop over the decades, good manners combined with common sense seems to rule the day. Like any other, the officer has a job to do and would really like to be able to complete his shift and go home like every other average person.
The only time I was ever pulled over that I didn't already know the reason was for a brake light that was out. Every other time it was for something that I KNEW I'd screwed up on, mostly speeding. Absolutely no sense in arguing with the officer over something you already knew you were doing wrong.
Window down, hands on the wheel, answer the officer politely, only reach for something when he asks (and tell him where I'm reaching), and a polite "thank you" when parting afterwards. (It ain't sucking up to thank the officer. It's simple good manners I extend to everybody.)
If he/she asks questions, don't lie or mislead. More often than not there will be cues you're not aware of which will tip them off to a lie.
That said, know your rights and know when NOT to answer.
Officer: "May I see your license and registration?"
Me: "Yes, sir. My license is in my wallet in my back pocket and the registration is in the glove compartment."
Officer: "OK. Do you have a weapon in the glove compartment?"
Me: "No, sir."
Officer: "Do you have any weapons in the trunk of your vehicle?"
Me: "Yes, sir."
Officer: "May I see what you have in your trunk?"
Me: "Am I being asked to consent to a search?"
If I'm carrying, then I comply with any state's law which says I must inform a police officer during an official encounter that I'm armed. I'll do this immediately after the officer makes his opening statement in a fashion similar to this:
Officer: May I see your license and registration?"
Me: "Yes, sir. I also have a permit to carry concealed and I do have a gun on my person."
And even if things do start out with an obnoxious officer, there is no profit in escallating the encounter through continued rude exchanges. He's the armed authority figure and the time to address this is LATER. Not in the heat of the moment when things can go really badly as a result.
For all that I've heard of people having negative encounters with officers during traffic stops, I have yet to have any that were anything except polite, professional encounters for the 3 1/2 decades of driving experience that has spanned a great number of states. I would have to say that negative encounters are the exception rather than the rule. (And never once have I been asked to consent to a search.)
