I wasn't defending it, just explaining the current state of that law.
Sorry, I had you confused with California Patriot who thought the Brady Act was constitutional.
BTW, another point to consider: rights are meaningless without remedies. If one regards the Second Amendment as absolute with regard to non-slaves (note that felons could be branded as slaves if states chose to do so), then the implied remedy is that any government action which violates the Second Amendment is void, any any official who seeks to carry out such action is a criminal acting without authority, and may be regarded as any other criminal.
By contrast, if one decides that the Brady Act is legitimate if and only if it doesn't cause delays for legitimate purchasers, what remedy will legitimate purchasers have when it does cause delays?
