Corrected entry: The bullet that hits the first lady was an "ice projectile". Ice bullets are impossible to fire because no matter how cold they were, they would melt almost instantly from the heated gases used to propel a bullet once it leaves the barrel.
Corrected entry: At the end of the movie Keenan shoots the bad guy in the back and then they say that he committed suicide to cover it up. How can he shoot himself in the back?
Correction: The only person Dunn (Wayans) kills in the last scene is Gen Woodword (Voight) and he takes him out with a head shot.
Correction: Wayans' character didn't know this, he just thought it was a dumb idea, but the real shooter didn't use an ice projectile bullet.
