Most attorneys will advise not to pay these civil demand letters. That is what I advise most of my clients. There is no requirement to pay until they actually have a civil judgement against you. It is often not worth there time to pursue it in court. Further it has no bearing on whether a criminal case is brought. Finally, payment of this demand will enable them to place you an a national registry for retail theft.
I do not see anything that would implicate you. Not offering information is different from hiding information. If you were to cover things up or lie for him, you could get into trouble. However, you have no duty, in most circumstances, to offer up information.
They can sometimes pursue criminal charges where the witness does not appear, but not always. Their ability to use it is hindered and they would not be able to use it. I have seen cases where they have had the detectives go to pick up the witness, particularly when there is a felony involved such as a burglary.
I agree with my colleague regarding obtaining an attorney. There is also the issue of a controlled substance in your system-which seems likely since there was a pot in your car and you have referred to it as a drug DUI. They would discover this through a blood test-as opposed to a breathalyzer.
You have been provided good advice here. Some offenses are considered deportable and some are not. I often see what I see as a lesser offense being deportable while I see offenses that I veiw as more serious being non-deportable. In a city like Atlanta, you can probably find an attorney that is well versed in both criminal and immigration law. Try finding someone with those credentials.
This should be addressed to a NY licensed attorney, since that is where this occurred. The most difficult issue with this is showing the NYPD did something wrong. In hindsight---they may have. Did they have enough to arest him at the time and failed to? That is the issue.
With very little exception , only summary offenses can be expunged in Pennsylvania. An attorney can review this and if it is a summary, rather than a misdemeanor, a motion to expunge can be made and likely successful. Otherwise, you must apply for a pardon.
