Add the word "Sucka" to the end of Lethal Weapon 2

At the end of Lethal Weapon 2, Murtaugh has his gat pointed at the South American Diplomat. The old man taunts Murtaugh by showing his credetials and cackles the phrase "Diplomatic Immunity". Murtaugh(who is pretty handy with the steel if you know what I mean) reponds by putting a bullet in the old bigot's head while saying "Just been revoked". And that's it. I always thought he should have said "Just been revoked, SUCKA". I would like to petition the producer, Richard Donner, to have the line added in and reshot or electronically dubbed in. Together we can get this done. Please help.
