I spoke to a cop about this and he told me based on the evidence I have and what the cops did I have a real shot at building a case against these cops. He said that the proper action in that situation would have been to take her to get her blood drawn. They also let a woman who with a head concussion who was visibly out of it drive home.
Either there is info you are leaving out, or, your associate is unaware of DUI law.
Simply being in a collision does NOT grant law enforcement the right to take someone in for a compulsory test. In fact, to do so would subject the police officer to criminal charges. It's simply not legal. The mandatory test is ONLY permitted AFTER an arrest is made, and the arrest has to be made with articulable probable cause to believe that the person arrested was both impaired on a chemical substance and driving. Absent the element of impairment, there is no PC for the arrest.
And, by "action" against the cops, about all that can be done is a complaint made to the employing agency. No law in any state MANDATES that the police investigate most crimes, much less provide you with a competent investigation. Their agency can take administrative action against them if they failed to meet the agency's standards, but there is no lawsuit or other action that can be had against them from what you have provided here.
She committed 2 criminal offenses. Not only did she have open containers in the car, but she was driving without a license. The cop told me those 2 should have easily at least gotten her arrested.
Open and empty containers??? I doubt that anyone could make a case for an open container with an empty one. As for driving unlicensed, okay ... but, didn't you say they were issued a citation? That IS an arrest in most states. Also, note that had she been arrested for being unlicensed, there would still NOT be a mandatory chemical test as the arrest would have to have been for DUI. And, the jail would simply release her with a citation.
And of course, there's the matter of not bothering to test whether she was drunk or not. And trying to impede with us taking pictures and video which is 100% legal and a cop can't stop you.
Again, their actions or inactions as it might pertain to an investigation is an internal matter and you and your mom are free to complain to their agency.
It's clear these cops did not want us taking pictures because photos are evidence. I don't know if this is a case of officer misconduct, or pure ignorance. Either way, they'll pay.
I would hope that they also took photos. But, in any event, they'll "pay" only if their employer chooses to discipline or retrain them. However, I also suspect they will have a different interpretation of events, so any chastising by their supervisors is far from a done deal.
It might not be evidence of a DUI but it is by law a criminal offence. And is that not enough evidence to at least draw a blood test? That is incompetency man.
Nope. The presence of an empty bottle proves that you found an empty bottle. It does NOT prove that the driver had been drinking from them at that moment. BY THEMSELVES they are not evidence of DUI. When taken in conjunction with other elements (such as the objective signs of impairment on the subject being interviewed, observed driving, FSTs, etc.) the bottles can tend to support the allegation.
Television and the media often imply a great many things that are simply not true. That is why some of us here like to help sort out fact from fiction, and to clarify why things are done the way they are.
Again, based solely on what you have written, I would have pursued this differently. But, I am a DUI instructor and have never lost a DUI case. That being said, I was not present at the scene and am not experienced in the laws of your state or its nuances in this area. It is possible that law and/or policy prohibited further action from being taken given an obvious head injury - especially since the FSTs would likely be worthless after defense counsel got through with it. If there were no other objective indicia of impairment (whether the officers looked hard or not) then no arrest for DUI would have been legal. No arrest for DUI would mean no chemical test and no proof of a DUI.
However, the lack of a criminal prosecution does NOT preclude your mom from suing the other driver if their insurance is insufficient to cover the damages. But, keep in mind that they may not have anything to pay an award.
