Remember, though, that carrying a gun—regardless of your level of skill with it—is no guarantee that you’ll prevail should you suffer the misfortune of getting caught up in a terrorist attack. The harsh truth is that by definition, the deck is already stacked against you. A terrorist intent on carrying out an attack is going to seek targets where the density of people is high, immediate escape is difficult, and there is little likelihood of immediate armed resistance. In other words, they’ll pick a target where most advantages are in their favor. They know that the only thing that will stop them is an armed response, so they’ll favor a target where that response will take time – at least enough time to allow them to complete their attack successfully.
