There are several aspects of every case that form the best practices for defending these cases, and we want to examine them from the start.
First, we want to know what the police have found and where did they find it? Then, we want to know why the police officers made contact in the first place, and how they came to be conducting a search. There are many 4th amendment issues, and it is never just a question of "did they have a valid basis for the search". Search and Seizure issues in Virginia are very complex, and only an experienced Virginia Marijuana Defense Attorney can properly examine these issues for you.
Finally, we need to examine how the police would hope to prove that the weed belongs to our client. Did our client make any admissions? Did they find it in a place that merely suggests that it was "probably" our client's weed? Were they actually smoking it or was it in their pockets?
