The first thing I thought when I saw this video of the gattling gun that pops out of the roof of the Suburban that follows the Presidential Limo was that perhaps there's an exception to a certain famous Michael Corleone quote.*
The Dillon M134D Gatling Gun is "a six barreled, electrically driven machine gun chambered in 7.62mm, capable of firing 4,000 rounds per minute."
This thing looks and sounds more severe than anything in Goldeneye, that's for sure.
*Listen, I'm not going to print it here. I want no accusations of threatening the life of the President. But if you need to, google "Michael Corleone if anything in this life is certain"
