Isn't SPECIAL COP...an alias for ITALY ARMED TO THE TEETH? I have this and WEAPONS OF DEATH to watch sometime. I watched the opening minutes of the Merli one and it looks great...movie wise anyways.
Like Stephen just said 'Special Cop in Action' is 'Italia a mano armata', never heard it called 'Italy Armed to the Teeth' before, sounds like a rough translation of the Italian title to me, which should really be something more like 'Italy: Every Man is Armed' or 'Armed Italy'...
You should watch them both Il Commissario, they're both great!
