During jury selection and you are a potential jury member, are you required to answer the question if asked whether you own a firearm or are a member of the NRA?
If you are directly asked a question, you might sit there silently or explicitly refuse to answer, and the judge may order you to answer (refusing the order would be contempt). A non-responsive answer when being individually examined by an attorney is to be corrected by re-asking the question, to get a complete answer. However, if the pool is asked a generic question ("Is anybody here a member of the NRA ~ does anyone here work for Google, raise your hand") silence (or not raising your hand) would be perjury. See People v. Meza 188 Cal.App.3d 1631, People v. Blackwell for example.
