It’s really not semantics. There is a difference in how a person should be treated that is
known to kill in order to escape and somebody that is believed to be non-violent and not likely to try violence in order to escape. As I said before, the
only reasonable assumption a cop can make for the former type is that he is likely to run outside shooting (discriminately or indiscriminately). That being the case, as well as the fact that he is believed to be armed and inside the building, where he could have easily come up with clothing from a student, the cops have to be as prepared as possible.
Moreover, your assumption that a handgun, in this case, is superior to a long arm is debatable. To my way of thinking, if the cops believe they are about to have an active shooter in the midst of innocents, the most precise and accurate firearm available is the way to go; maximizing their chances of taking out the shooter with minimum innocent casualties. I don’t think you can argue that a long arm beats out the handgun in that category. Granted a long arm is slower to deploy than a handgun. The flip side to that coin is that if/when the cops have to use the weapon, the long arm is far more likely to be on target and stay on target than a handgun. Life is full of tradeoffs. In this case, I think the choices made by the cops are entirely reasonable. They chose long arm over handgun, which I willingly concede is a debatable choice, but one I agree with given the circumstances and could easily see myself making were I there. They chose to be on target as students were running from the building. Again, a debatable decision, but
fairly reasonable given the circumstances: a shooter likely to be running out with all the other students and if so, more than likely to begin shooting indiscriminately. A rapid and precise takedown in that situation is paramount.
And do try to remember, I have been shot at by badguys…
So have others of us. What does that have to do with the price of tea in China? Are you suggesting that somebody that hasn’t been shot at (regardless of which side they come down on in this situation) is somehow less able to decide the best tactics? Or are you perhaps suggesting, by saying so multiple times, that to have been shot at somehow makes you better than those that haven’t? Seriously, I’m asking so you have the chance to state your view. By bringing this point up on several occasions, you obviously think it makes you better able to opine, or
at least more experienced than those that have not been shot at.
…and I get to see my local officers shooting at the range (come to think of it, I've seen a few folks that looked a bit hood-like there, too -- lousy shots); I don't have to speculate. Getting the first shot doesn't mean much unless you can hit what you're aiming at.
Which is exactly why I think aimed-in with a rifle is a reasonable choice to make. It allows the cops their best chance to be the first to shoot, their best chance to have their shots on target, and their best chance to bring the target down quickly.
