My first reply was because, over on
https://forums.officer.com/ , I see cops commenting a lot about non-cops decking their vehicles out with emergency lights and some going so far as playing cop.
Without exception it really pisses them off and they caution others about stopping in remote locations for questionable vehicles/officers.
The hard part is if you don't stop for the real officer that's as described above. So what do you do? If you're driving, call 911 and explain what's happening and your concern about the unmarked car trying to pull you over. On a bike it's tougher. If you're in a populated area, indicate that you're pulling over but do it in a well-lit area with lots of people around (preferably a police station). That does 2 things, it makes the stop safer for the officer and you as it gets him/her out of the traffic and you where there's a higher chance of help if it is one of those fake cops.
The remote areas are another thing. Since there's nothing nearby to go to, you're stuck. The trade off is that there's also less risk of it being anything other than an officer if you're remote enough, since sensible people (leaving out endurance riders and non-cops) wouldn't want be out there much more than the general population.
But the forum is rife with conflicting responses. In a thread about recent assaults by pretend cops, they'll give the advice about finding a safer place to stop. In a thread about failing to stop for an unmarked car, they'll bag on the driver/rider for not stopping right away.
That's a pretty good answer Bounce. Just remember that a lot of the cops that are active in "officer" forums are bordering on not being right in the head. Just like this forum, there are a lot of tools saying things that are either blatently stupid and wrong, or just misconstrued. For most of us, being a cop is a job. For some, being a cop is their entire life. Those guys concern me. I say this with a grain of salt, because I worked internet crimes for a few years and cringed everytime I got a case involving some guy that was a cop or claimed to be a cop. This is still the internet.
That being said, people buying lights and running around acting like cops does happen. It does not happen with much frequency. We had a guy in Albuquerque doing it on a large scale just a while back, and he was caught. Other than him, its pretty in-frequent. What does happen is someone will break into a cop car and take a raid vest or jacket and then that guy and his buddys will crash a drug dealer's house pretending to be cops and steal money and drugs. But...People taking the time and money to equip cars with lights just to pull people over...There's a lot of risk involved in that.
So...The CSI guy was totally within his rights to pull Synthian over. Just because we get moved from a division like patrol to something like CSI does not mean we are not still cops. A lot of our SWAT guys are homicide/violent crimes detectives. I have been off patrol for 6 years and I still stop lots of people with my unmarked car. I issue lots of citations too. As far as the "certified" speedo...Yup. Every manufacturer that makes a "police vehicle" installs a "certified speedometer." What that means is the speedo is accurate to within 2mph (+/- 2mph). Unlike our FJRs and your Honda accords that are a little optomistic. We verify our speedo readings with radar and we only use OEM sized tires, so there is no reason for them to lose calibration. IF we end up having a tranny replaced or something like that, we have to send the car off for re-calibration.
As ChecksWrecks said...Judges love "pace" citations. I have yet to find a court that does not allow our speedometer reading as perfect evidence of speeding.
So...Who makes police cars? Well, Ford makes the CrownVictoria and the Expedition and the Explorer for police duty. I know we have some Fusions with lights running around, but I donno if those are "police packages" or just govenment cars equipped with lights. Equipping a non-police package car with police lights voids the warranty, so I donno if they did that or not.
Dodge makes the Charger, and Chevy makes the Impala and the Tahoe. For the most part, most cops with the ability to pull someone over will be driving one of these cars: CrownVic, Expedition, Explorer, Charger, Impala, or Tahoe, and depending on what state you are in, they may have an obvious "Government" plate.
As far as stopping when you see lights...Here is the deal in NM: Statute says that when a person sees red flashing lights behind them, they will pull to the right and stop. Immediately. We cite for people that don't do that. However, usually that is people that just refuse to move for ambulances, or are purposely trying to be difficult, and most times, it is from a marked unit anwyay. But tell me this...If a cop car comes up from behind you with lights on, how do you know if it is marked or unmarked? All you can see is the hood, and those are very seldom marked. So...We use a degree of what is resonable.
The other day, I pulled a lady over for blowing through a red light in early morning traffic. I have an unmarked Impala and know that the interior lights make some people nervous. So...I waited until after she got on the freeway and turned on my lights so she wouldn't pull over on an on-ramp. She maintained speed, but did not accelerate. She didn't stop for a while. I hit her with the siren a few times and eventually she pulled over. I was wearing "civilian" clothes which consisted of tan BDU pants and a black department polo that showed my badge. I also had my metal badge showing. All I have to be wearing is my badge, and driving an "authorized police vehicle." The tan pants and black polo are division uniforms and are authorized.
When I approached her car, she would not roll the window down and told me she was on the phone with 911. Since I had called out the stop, they verified to her that I was actually a cop. I even showed her my comssion card...The lady ended up getting a warning. She had her head up her butt and didn't even know she had run a light, so she didn't know why I was stopping her. When she saw me, she called 911 and verified I was genuine. What she did not do was speed up, start driving erratically, or do anything stupid.
Those of us driving unmarked cars with interior lights know some people are genuinly concerned but some will not stop just to be difficult. The actions taken by those people are distinctly different. So...My advice? If you are not sure, activate your emergency flashers and slow down a little. Get on the phone and see if 911 knows anything about you being stopped. Even if it is real, they may not, because depending on the agency, you may have the wrong center. Here, if you call 911 wihtin a 10 mile radius of Albuquerque, you will get Albuquerque Police, but it may be Airport Police, Sheriff's Department, State Police, UNM Police or someone else pulling you over. The county lines north and south of Albuquerque are within a couple miles of the city limits and it could be tribal police, or another county all together.
So...Find a decent spot and stop. Let 911 know where you are. Keep your windows rolled up and watch how the officer approaches. Once at the window, ask the officer for a badge and commission card. If they get pissed off or refuse, leave. A real cop will understand and show you his information. DO NOT drive off just because they are in civilian clothes. I have stopped a few people just to tell them something was wrong with their car, and a few times, I have been in jeans and a shirt. Most guys making stops will be wearing a vest though...I always have mine. I also always have a badge visible.
If you're on a bike, just keep your feet on the ground and your hands on the bars. If the guy isn't really a cop, you can accelerate out of there faster than he can chase you.
For the record, Symian left some important things out of his traffic stop story. I25 just north of Tramway is a cluster. They are still doing some sporatic construction and just widened the freeway to three lanes. The speed limit is only 70 and then drops to 65 right about Tramway. There is a lot of traffic, and 85 in that area is unreasonable. It is not out in the middle of nowhere, it is right at the entrance to Albuquerque, and there are lots of dummies and lots of traffic. When I stop people for going 85 through there, they get citations.
