Drug charges can result from a number of different incidents. A sting, a routine traffic stop or an investigation may lead you to be charged with possession or another drug-related crime. Typically, to file such charges, law enforcement will perform a search and seizure to collect evidence against you. This practice, though typical, is controversial--and it may be unfairly performed. According to the United States Commission on Civil Rights, police in New York City perform thousands of stop and frisk or search and seizure procedures every year. The legality of such interactions is worth questioning, though, and there are a few things you should know if you have been subject to a search.
