In July 2010, the ACLU and the ACLU of New Jersey filed a lawsuit on behalf of an innocent Camden, New Jersey man, Joel Barnes, who was jailed for more than a year as the result of having drugs planted on him by police officers later implicated in a large-scale evidence-planting conspiracy affecting nearly 200 other Camden residents. Mr. Barnes is seeking compensatory damages, as well as injunctive relief designed to prevent such conduct among Camden police officers from occurring in the future.
