The left cries for bigger locks, bullet proof glass, and more screening of personal and confidential information. Because they believe. They believe if they just know enough about you, and invade every nook and cranny of your life, they can stop you from doing whatever it is you might do that they don't like. The left will not be satisfied until a fortress has been built to keep out "the bad guys." And then they will discover, to their own horror and demise, that the horror, the evil, resides WITH them.
The tragedy could have and would have been stopped with laxer gun laws. With laws that made it second nature for every school in america to have armed principals, secretaries, and teachers.
don't forget...it took the police 15 MINUTES!!!
