Whether you intended it or even realized it, that's an implied threat.
No threat was implied - what I was trying to point out is that if you argue with an officer and try to get him or her to change their mind regarding a TC violation - it's probably not going to happen. In fact, I personally know of no officer who has changed his or her mind because someone is arguing with them that they don't agree with the law, like the law, weren't breaking the law, or whatever reason they have. That's what the court system is for, or getting the legislature to change the laws. Just the fact that someone argues with me on the side of the road doesn't mean I'm going to change my mind as to whether they get a ticket or go to jail.
In your heart of hearts, you probably could name a few officers you've met, who would effect a custodial arrest over a speeding ticket if they didn't like the driver's attitude.
Have I seen people "talk themselves into jail" you bet I have. On our department for us to "jail traffic" someone there has to be five TC violations for that to happen so you really don't see it that much. Whenever you do it's usually because someone just needs to go to jail ie: no DL or expired DL, registration not current, no insurance, speeding, lights burned out, and so on. There are lots (if not most) departments that would arrest you for only one or two of these offenses (other than speeding) so we're pretty lenient in this aspect.
Do you really think any law requires collection of this information? Some might require the officer to request it, but I frankly do not believe any law requires the driver to divulge it.
My experience has taught me that if a department or agency has a policy (such as requesting someone's information) and it is illegal for them to do that, someone usually sues that department or agency and gets a court ruling to prevent them from doing such in the future. In this day and time I can't imagine that someone hasn't tried to challenge this issue, and the courts must have ruled that it is indeed legal for them to collect it.
One thing you might want to remember is just because something is legal (or illegal) in another state or part of the country, doesn't mean it's the same in Texas. A good example are DWI or sobriety checkpoints. In many states they have been ruled legal and in others they have been ruled illegal. There are lots of states with state constitutions that are more restrictive than our federal one - Texas being one of them. There are certain search and seizure laws that we have in Texas that are more restrictive on LE than the federal ones are. DWI checkpoints are the same - you just don't see them in Texas due to court rulings. I understand that might be changing in the future but for now we don't do them.
It's the same with traffic laws and procedures. I've had people tell me plenty of times on traffic stops that, "I'm from Oklahoma, or I'm from Arkansas and we don't have to do that where I'm from." I love kidding with these folks especially when I tell them that the reason that I stopped them was because they ran a stop sign or a red light and they reply something like, "Oh, I'm from Oklahoma." I usually respond with, "Oh, you don't have stop signs in Oklahoma?" After a few seconds it sinks in as to exactly what they said and we both get a good laugh out of it.
In all my years of writing tickets or completing accident reports I've never had anyone say that they weren't going to answer a question I needed to complete a ticket or report. I'll have to check with some of our traffic enforcement officers that write tickets day in and day out to see if they've ever had this happen and what they would do if it did occur.
