Occupy Trenton, which has kept up a presence in a public park across from the Statehouse for three weeks, tried to convince a state judge Wednesday to stop police from confiscating its cameras, protest signs and other items.

After a hearing, Mercer County General Equity Judge Mary Jacobson reserved decision on a request for a temporary restraining order to bar the state police and the Department of Military and Veterans Affairs from infringing on the protesters’ First Amendment and other constitutional rights and from enforcing allegedly invalid and ad hoc restrictions on the use of a public forum.
