Question: Do Presidents make last-minute trips to other locations in the world? Or would that not be possible due to a safety concern? In reality, would somebody else attend the funeral in the President's place?
Answer: I worked security in the 1990s, in Houston, Tx, when Clinton was in office. I was working the George R. Brown convention center. One day I went to get my paycheck, when I spotted several men surrounding the building. I asked if there was an event inside the building, they said they were Secret Service agents and there was a possibility that the President may make a visit. I asked, really. They said it was a possibility, he might stop by but could change his mind at the drop of a hat. Those men waited for nearly ten hours all day and in the end, Clinton didn't come.
Question: Can someone be shot through the side and just duct tape the entry and exit holes? (Wouldn't the bullet have mushroomed in the body and not exited anyway?) If there were a real gunshot wound like that, how long until he bleeds out?
Answer: Duct taping the wounds may seal the injury and hold the bleeding, but it may not be effective. If something along the lines of this would happen in real life, it would be best to tend to the wounds properly in case of infection. Whether or not the bullet would get stuck inside the body depends on if whether or not the bullet hits something, that would cause it to get stuck inside the body. How long until someone would bleed out in real life depends on the severity of the gunshot wound and whether or not something major was hit.
Question: Why are the officers wearing dress blues in the beginning of the movie? The replacement commander of the 110th has a chest full of ribbons...The black military police officer at the command center. Everyday military officers would be wearing Class A's or fatigues.
Answer: Although it's technically a mistake, it is common in films to show military officers in dress uniforms with medals and ribbons to show that particular soldiers are important. A layperson may not know military uniform protocols but they can certainly tell that dress uniforms with a lot of medals signifies high rank at a glance.
Answer: Once she saw the gun and knew how crazy the game was, she formed an idea that someone's would get shot and believed that it would be her.
