Finally! 16 pages to read before I wanted to post my opinion.
The first and foremost thing I want to get out there... Cops are regular guys like you and me. Some are Idiots (please see Webster's definition if you don't know what that word means), some guys are in the middle and just collecting a paycheck and some guys are pretty good at their job.
I've read every post on this thread. It is important to know that an officer cannot stop a vehicle unless he has probable cause (a violation) or reasonable suspicion of a crime was committed or will be committed.
If a cop asks where are you going, it is a question in an attempt to catch one in a lie. Example: COP: "Where are you going?" DRIVER: "Home" COP: "home is three blocks behind you, why would you be driving away from your house if you were going home." A small example but you get the point.
If one cop pulls you over and more cops show up, that doesn't mean that he called them, they are just backing him up... or he called them because he thought a arrest was going to be made and the driver was being a smarta$$ by telling the cop that he sells rocks. At the time a driver admits to selling an illegal substance, there is something called a V-NOTE, officer can and will post onto a license plate response for officer safety information. Where there are drugs, there are guns.
If there is more than one cop and you are mad because he has backup, think of this. If there are 20,000 people in a community and there are 20 Patrol officers, that's 1 per a thousand. But on a shift, there may only be 4 cops on for that 8 hours. So now it's 4 guys responsible for 20,000 people. If you had to deal with a potentially dangerous situation...would you want to be alone?
For all of you who have made STUPID comments like, Cops pull people over for tints because they can't see the driver and it makes them mad or jealous. JEALOUS: Yes because cops can't have tint's, they are illegal. Some Departments like Chicago suspend cops for having illegal items on their vehicle or even having a tail light out. MAKES THEM MAD: Wrong, all serious enforcement started with Captain Robbie Edward Bishop of the Villa Rica Police Department in Georgia. He was innovator of the current drug interdiction policies used by the 5-0 all over the country and probably has the record for most drugs seized. He walks up to a car with tints and gets shot in the head right through the drivers side window because he couldn't see the guy pointing the gun at him. The guys in Collinsville Missouri are hard core with his policy and have gotten more drugs from those interstates than the border patrol. If tints are illegal in your state, your most likely going to get pulled over. Why you ask, because it's illegal... and quota's.
Time of day... or night more specifically. If it's past midnight, some states allow it as P.C. (probable cause). It is unusual for people to be out at that time of night. The P.C. is intensified if the area is a high crime area.
One of the things that all of you haven't even considered, you do not know the law as well as the cops. Here in Illinois it is illegal for any vehicle to modify their exhaust system. It is illegal for wheels or tires to exceed the boundaries of the body of the vehicle.
There are also laws pertaining to correct vehicle height, type of lights, seatbelt, visual obstruction of the windshield (for those of you who have radar), amount of time/distance required to signal and when you are to pull over (for the guy who wanted to get home before he pulled over, it's called fleeing and eluding, you see blue and reds, you stop or risk dragged out of the car) and my personal favorite which is also a favorite of NARC cops that need P.C. is the License plate light. I could go on for quite some time with these.
Unless you sit down with the (insert your state here) Vehicle Code book and learn all the B.S. that cops can pull you over for, your probably not in the know. AND THAT'S OKAY! 96% of people don't know that proper traffic laws. The other 4% are most likely cops.
I'm not saying there isn't racial profiling, (although it's difficult to see the driver when they pass a cop by at 20mph over posted) or through tints. I'm not saying that there are no bored Barney Fife's in Mayberry, all I'm saying is that maybe you should go to citydata.com and check your city for the most prevalent types of crimes. In small rural towns, it has been known that it is the most likely place to make Meth because of the seclusion and the easy access to Anhydrous ammonia. If your in the City like I am, well it's a free for all what they could ask you. Most of the time the cop is just asking to ask because there is a suspicion. If the very Beautiful and expensive 300C is rollin through Flint Michigan in a high crime area where drugs and poverty is the norm, well the cop might ask about drugs or weapons in the vehicle or where you might be going.
Try to give the cops the benefit of the doubt. Some cops are ridiculous with the little B.S. that they enforce, some have a good reason, but all of them have the CHOICE to take away your driving privileges. Oh, I forgot to mention that driving is a privilege and not a right. If the cops pulls you over for B.S. and lets you go, feel lucky you don't have to spend $55.00 - $150.00 on a ticket or 200+ on an attorney.
I will answer any questions you guys have and try to put as much as I can in perspective.
