Where did I say it was a numbers game regarding innocent lives? And you're missing the point regarding Ft. Hood.....DESPITE being surrounded by trained soldiers with ready armament, you had a mass killing with an armeed perpetraitor. So for people to theorize that some civilian with a CWP or the like would save the day in Colorado is absurd.
I''m not referring solely to the theatre shootings but to mass shootings, in general, and how others being armed would have reduced the numbers of victims. Following are two examples.
(Excerpt) The Luby's massacre was a mass murder that took place on October 16, 1991, in Killeen, Texas, United States when George Hennard drove his pickup truck into a Luby's cafeteria and shot 23 people to death while wounding another 20, subsequently committing suicide by shooting himself.
Hennard also approached 32-year-old Suzanna Hupp and her parents.
Hupp reached for her revolver in her purse, only to remember she had left it in her car to comply with Texas law……Hennard reloaded several times and still had ammunition remaining when he committed suicide by shooting himself in the head after being cornered and wounded by police. (End)

There's a definite possibility it could have ended right then and there if the lady had her revolver with her.
Virginia Tech massacre
(Excerpt) Cho's first attack after entering Norris occurred in an advanced hydrology engineering class taught by Professor G. V. Loganathan in room 206. Cho first shot and killed the professor, then continued shooting, killing nine of the 13 students in the room and injuring two others. Next, Cho went across the hall to room 207, in which instructor Christopher James Bishop was teaching German. Cho killed Bishop and four students; six students were wounded. Cho then moved on to Norris 211 and 204. In both of these classrooms, Cho was initially prevented from entering the classroom by barricades erected by instructors and students. In room 204, Professor Liviu Librescu, an Israeli Holocaust survivor, forcibly prevented Cho from entering the room. Librescu was able to hold the door closed until most of his students escaped through the windows, but he died after being shot multiple times through the door. One student in his classroom was killed. Instructor Jocelyne Couture-Nowak and student Henry Lee were killed in room 211 as they attempted to barricade the door. Eleven students died in room 211; the six students who survived all suffered gunshot wounds. (End)

Room 206, 207, 211 and 204. He basically cruised the halls and if just one teacher was armed it might have ended quickly.
