Hi and thanks for the quick reply.
I think the police handled this badly, but that said, the initial encounter doesn't look unlawful to me.
The police don't need very much evidence to approach a car. They just need something more than a hunch that something may be going on. Here they had a legitimate reason to approach the car. It was stopped and that meant that something was irregular, though not necessarily criminal.
Once they approach they are allowed to ask for a license and registration and to pat you both down for their safety as well as to do a limited search of the car.
It doesn't give them grounds for a more full search, and it's possible, depending upon the circumstance, that the search and the retrieival of the heroin fro your husband's pocket was performed in violation of your husband's rights. It's difficult to say without details.
As for Miranda, Miranda only stands for the fact that a defendant who has been arrested does not have to submit to police interrogation
. If there was no interrogation about the heroin, then Miranda doesn't apply and the warnings would not have to be read.
If your husband suffered medical damages through the officer's failure to get him medical attention, you could contact a civil lawyer and sue the county to get that money back. If what could have happened to him by virtue of his blood pressure didn't.fortunately, your best bet would not be to sue but to simply report the police for harassment and irregularities to their supervisors, to Internal Affairs and to your State Attorney General's Office to provoke an investigation
to look into their practices.
