According to ABC, recent studies of school and other shootings has lead to new (or not so new, if you watch this sort of thing) profiles of school shooters.
So confident that the studies are reasonable and accurate, police forces are changing tactics to adjust to the conclusions. This is important because real, tangible consequences (like, say, getting killed) can result for responders who get this wrong. That is, unlike those who want Guantanamo prisoners released now, just not in their own neighborhood, the police may get killed or sued if their behavior doesn't dovetail with known risks.
Classified as "active killers," these attackers:
"Now tacticians believe the signs themselves may be an invitation to the active killers"
For police, the studies tell them that aggressive action must happen as quickly as possible as the killers are likely to quit the fight if the police or civilian resistance shows up, or, they will rack up a body count for as long as armed resistance doesn't materialize.
People who think about the world in terms of their pretty intentions endanger the lives of the rest of us, for murders are unconcerned with the trivialities of gun control policies. For policy makers, it means that gun free zones can kill people.
For civilians, it means we should hold policymakers personally responsible for deaths that occur in gun free zones as a result of an inability to guarantee the safety of the public. It is unjust to tell people they cannot possess the means to defend themselves and then fail to do an adequate job of defending them.
THIS IS ALL QUITE PREDICTABLE
Not to paint with too broad a brush, but one of the differences between Conservative and Progressive thinking is that the former deals in incentives and the latter deals in intentions.
The behavior of active killers matches up perfectly with the expectations of Conservative thinking.
All of these things are based on a fundamental idea that one can derive from Judeo-Christian principle or from Neo-Darwinism: humans are violent, ugly creatures capable of horrendous evil. Call it The Fall or the inherited traits of our cannibalistic, extraordinarily vicious relatives in the animal kingdom, it all amounts to the same thing: civilization is clothing on a hairless monster.
What I would be curious to see is how these issues are understood by Progressives. Can Progressive ideas about the world explain these results? I think #1 above is particularly problematic. Most of the responses I see to this issue gloss over the fact and recommend extending the absurdity of "gun free zones" to the entire population. That is, since creating a small gun free zone only resulted in massive deaths committed by killers who brought guns into the gun free zone, the conclusion isn't that gun free zones get people killed, but that they should be extended to the entirety of the country.
With the caveat that the State will have all the guns, and therefore a monopoly on the power to deal death. All for the greater good, of course. Don't you worry yourself none.
(The question then remains as to whether that is effect or intent.)
