Thank you for coverage of the Aurora, Colo., theater massacre, not far from the 1999 Columbine massacre. It is most tragic that yet a third shooting occurred in the Littleton area after those of 1999 and 2000. The 12 dead and 58 wounded make this one of the most horrific shootings so far.
Not all guns should be legal, and all should be regulated. Guns vary in range and penetration. In a 1984 Rifle Firepower Magazine article, six small arms were fired from five to 100 yards at a sturdy 1967 model car. Guns tested were a 7.62-mm AR-10 and a 5.56-mm M-16 rifles; a .45-caliber M1928 Tommy gun and a 9mm MP-5 submachine gun; and a 9mm Browning and a .45-caliber Colt pistol.
Test-fired head-on, then obliquely, at the windshield, the AR-10 penetrated both directly and obliquely and destroyed the dashboard. The M-16 failed to penetrate either directly or obliquely, but could cause flying-glass injuries. The submachine guns penetrated directly, but not obliquely. And the pistols penetrated directly, but not from an angle.
Test-fired at the drivers side door, both rifles zipped clear through, cleanly exiting through the opposite panel. Both submachine guns cleanly penetrated the rear door and lodged in the opposite panel.
The Aurora assassins semi-automatic rifle was closest in performance to the AR-10. It carried 100 rounds in an illegal clip.
Come on! Do we want such power in criminals hands?
