From your linked article, first paragraph: >Lieutenant-Colonel Antonio Tejero led 200 armed Civil Guard officers into the Congress of Deputies during the vote to elect a President of the Government. The officers held the parliamentarians and ministers hostage for 18 hours, during which time King Juan Carlos I denounced the coup in a televised address, calling for rule of law and the democratic government to continue. The royal address fatally undermined the coup. Though shots were fired, the hostage-takers surrendered the next morning without killing anyone. I really do not see the equivalence here at all. Only through a highly partisan stretch could a professional gymnast make this leap.
