Every time one of these threads comes up, I always see people say, "Get an attorney." I have never understood that. Granted, I only have experience in about 6 court jurisdictions, but in my 18 years as a cop, I have yet to see an attorney do anything of significant value for a simple traffic ticket.
For crimes, absolutely, no question about it, the right attorney can make all the difference in the world. But, he was given a speeding ticket, not charged with reckless driving. Remember, a speeding ticket in most jurisdictions is only a violation, which is a pecuniary offense, meaning the only punishment is monetary, with the possibility of license suspension. There is no jail time possible with a violation.
Oh, and for those of you that suggest hiring a lawyer so you can subpoena the entire world. You better hope it works because the court (judge) doesn't take too kindly to a person that ties up valuable court time by going on a fishing expedition. If the lawyer (or you) does some research and learn that the officer wasn't properly trained in the use of whatever device, then by all means, go for it, the officer shouldn't have been using it in the first place. But every time I have had one of those cases (usually it's when the lawyer himself gets the ticket), the judge is very rigid, and not accommodating. But then, in my case, I was appropriately certified, did use the device properly, and had all the necessary records to prove the case.
Granted, I'm spoiled in that the agency I work for now, as well as most of the surrounding agencies, have a pretty good track record for professional behavior, especially in making sure that certifications are maintained, etc. Other areas may be what's feeding the storm of "get an attorney", I don't know.
