Killing Gandhi

You wait to see what the man does. Thankfully he does not see that you are paying attention to him. You can see that he goes through cycles in his brain of what he wants to do. You are watching intently at the man, so much so that you fogot to walk with the group. Just as you realize this, the man titens his grip on the weapon as if he is ready to fire. Seeing this you know that this could be the opportunity, but you think that if he sees you diving for Gandhi he will surely shoot. Should you wait or go for it?
