- James Fox: When a mass shooting happens, we search for answers
- He says investigators might be able learn about motivation by talking to the suspect
- Fox says many will advocate either gun control or more use of concealed weapons
- He says it's very unlikely either solution could prevent mass murders

(CNN) -- There are few criminal events as stunning and frightening as a mass shooting. The suddenness, randomness and unpredictability of episodes like Friday's early morning massacre at an Aurora, Colorado, movie theater cause us all to wonder whether any place is safe.
In our search for some pattern or commonality to these tragedies that might help us make sense of what appears so senseless, we invariably seek answers to such questions as: "What would inspire someone to commit such a dreadful act, one that was clearly planned in terms of time and place?" and "Are there measures that would reduce the likelihood of such events or at least reduce the carnage associated with them when they do occur?"

Because the shooting suspect was alive at the scene -- many mass killers commit suicide -- we might learn a lot more than usual about a motive for mass murder. Of course, that will do little to help us prevent future events. (The number of mass murders in the U.S. has remained fairly steady, averaging about two dozen cases a year since the mid-1970s.)
Even though there is a general profile that typifies these perpetrators, their exact identities become crystal clear only in the aftermath.
If one thing is predictable about mass shootings, however, is that they will spark arguments from gun control advocates and gun rights groups alike. Both sides of the gun issue will probably view this tragedy as one more example of why more or less gun control is the answer ... and both sides will be wrong.
Tighter restrictions on gun purchasing -- for example, eliminating multiple gun sales and closing the gun-show loophole -- may help reduce America's gun violence problem generally, but mass murder is unlike most other forms of violent conflict.

Mass killers are determined, deliberate and dead-set on murder. They plan methodically to execute their victims, finding the means no matter what laws or other impediments the state attempts to place in their way. To them, the will to kill cannot be denied.
At least 12 people were killed and 38 wounded when a gunman opened fire during a screening of "The Dark Knight Rises" early Friday at an Aurora, Colorado, theater, Police Chief Dan Oates said. 
University of Colorado Hospital spokeswoman Jacque Montgomery said that all of the wounded had from gunshot wounds, ranging from minor to critical, she said.

Witnesses told KUSA that the gunman kicked in an emergency exit door and threw a smoke bomb into the darkened theater before opening fire.

Witness: He pointed gun at my face Mass shootings have been exploited just as effectively by pro-gun groups to promote legislation allowing ordinary citizens to carry concealed weapons in public places. Concealed-carry proponents suggest that an armed citizenry would deter criminals or at least reduce the death toll.
While logical in theory, in the chaos of the moment, few gun owners would be prepared to mount an effective counterattack. And in a crowded setting, such as the movie theater clouded with tear gas and smoke, it would be virtually impossible to distinguish the bad guy with a gun from the good guys with their guns.
In the short term, there will probably be security specialists who will recommend ways in which our public spaces could be better protected. Sadly, mass shootings have occurred in shopping malls, schools, restaurants, health clubs, churches, courthouses, post offices, almost any place that people congregate. None of us would wish to turn our public spaces into tightly secured fortresses.

It is also unreasonable to expect that we would begin a campaign to round up all the guns or all the potentially dangerous people who might have access to guns. Mass murder is regrettably one of the painful consequences of the freedoms we enjoy.
