No Difference!
REEDSRUS8:
The responses from both Army Judge and Mightymoose were quite correct and I would emphasize specially Mightymoose's with regards to Miranda reading and the time taken to get to the police station.
Unless you were questioned unreasonably, were interrogated, or was somehow coerced or forced to confess by the peace officer(s) before you were read your Miranda rights, you would have a valid claim, but as said already, it was not needed immediately in this case as your blowing 0.9 is prima facae proof of your indiscretion and, the officer(s) did not solicit any information out of you by stealth or otherwise from the time you were handcuffed until you arrived at jail to be processed.
And I do not mean to make light of the situation, but you should consider yourself very fortunate for spending only an hour in the back the highway patrol unit, because that is nothing this day and age, a walk in the park. You should also feel fortunate for the fact that in California the first D.U.I. resulting in no injury or death is charged only as a misdemeanor, so you didn't even have to spend three to five days in jail (depending where the weekend falls) before seeing a judge and were released after only 9 hours.
All said and done, you are welcome to do this and that, continue or not continue, plead guilty or not guilty, hire an attorney or decide to go solo, but let me assure you of one fact, which is unless you blew anything less than 0.8 and were arrested under extremely questionable circumstances like you were sitting in the car in your own car port when arrested, the D.U.I. conviction will follow without question as the offense is taken incredibly serious by the penal system and the room for wiggle worming is therefore next to nothing.
I would therefore strongly suggest that you do not delay the inevitable and get to have your day in court as soon as possible; take your medicine and be done with it and in the process save yourself thousands of dollars in attorney's fees. The arraignment is conveyer belt stuff and the process is very much painless, quick, and dignified and it is not as if they will be stringing you up from a pole.
You have been very contrite and have already shown a lot of respect towards the court by taking AA classes, which will leave a must attend two hour M.A.D.D. seminar (Mothers Against Drunk Driving) and the 3 different classes a week over a 12 week long period, which you can combine to do on one Saturday and get on with other things the rest of the week, which will now also include shopping for a mandatory SR-22 car insurance and finding rides to work for the 90 days that your license will be suspended for.
D.U.I. is a horrible experience and you would want to get it over and done with as quickly as possible; but believe me when I say, that it is also an absolute blessing in disguise.
It was for me and I am now, and will be forever thankful to the officer who arrested me 12 years ago.
