Query: Post-Detection SETI Protocols & METI: The Time Has Come To Regulate Them
  Both   Regulations governing METI are weak or non-existent. Post-detection SETI
protocols are non-binding and too general. Vastly increased SETI capabilities,
Chinese involvement in the field, and an intensified effort by METI-ists to
initiate radio transmissions to the stars are among reasons cited for urgency
in addressing the question of appropriate regulations. Recommendations include
regulations at the agency level and laws at the national level as well as
international treaties and oversight.
