Yes. Rhode Island obstruction charges can be defended through several angles. The lawfulness of the underlying police conduct is critical — if the officer was not acting lawfully (illegal stop, unlawful order), obstruction of that conduct may not be criminal. Defense angles include challenging the lawfulness of the officer’s action, contesting whether the defendant actually interfered (running from police is not always obstruction), arguing First Amendment protected speech, and challenging the intent element (negligence is not the same as willful obstruction). Obstruction stacking charges can often be reduced or dismissed when the primary charge is defended successfully, since the obstruction was tied to the underlying case.
