Several things seem to have been overlooked. The first is physical, and has to do with firing the weapons themselves. While the caliber of the weapons was small, there are key components to the weapons that directly affect the firings.

With the 9mm there is a jerk upon firing that has a tendency to twist the weapon to one side, which is why the user's most effective use of the weapon happens when it is held with both hands - (the hand that will pull the trigger being braced by the other) which is used to grip the wrist and confines the kick to controllable minimums.

In both cases (22 & 9mm) the weapon requires two hands to eject the empty cartridge and insert the new magazine. Ex-police officers with a great deal of practice have said that it's possible to develop a nearly seamless procedure, but only after a great deal of experience. Basically this information tends to rule out the simultaneously use of two guns - under any circumstances, except that of just having a second weapon in reserve. 

The larger issue of real target training versus computer simulations leaves out several other physical points that matter. For instance accurate shooting requires eye-hand coordination and extreme concentration: both of which must be learned in relationship to firing any weapon. If a gun is used for self-defense and in close range - just firing the piece is almost automatic, but to use it offensively to KILL other people, especially people that are trying to flee or to attack the shooter - this requires real experience over time with the particular variables of the weapons to be used. For instance the amount of pressure placed upon the specific trigger, before the shot will be fired is critical, along with how much of a kick or twist is involved in any particular combination of the weapon and the particular ammunition being used (different loads can react very differently) in terms of the performance of both the weapon and the shooter.

The physical requirements are something that most people acquire first in other areas such as sports or play - apparently Cho did very little of this in any way, prior to his arrival at this point in his own death. What seems to have happened here is that Americans relied on what they "knew" from too much TV and or bad movies to make their judgments about the ability of Cho to pull this off - believably.

There's a lot of information that the public will never see - because it will be part of the police reports but probably never will make its way into the public record, For instance how many of the bullets came from each gun. Also there appears not to have been any security video-tapes, so we'll never know if there was literally more than one shooter. Lack of video-tape also means that there can be no real-time reconstruction as to who was shot where, and most importantly when. Because if people were being killed at the same time in different classrooms then that would have to mean that there was more than one shooter.

However the most dire and condemning evidence is also in the hands of the police. Early on it was said that the face of the "shooter" was so disfigured that "it was not possible to even tell what nationality he was." That kind of damage could not have been done with either or both weapons - and indicates strongly that either there was a small bomb used to destroy the face, or that someone else, besides Cho, did the mutilation.

Then there is the lengthy schedule of business for that day - supposedly accomplished only by Cho. First he goes to a dorm and kills two people (probably using the 22), to attract less attention. He escapes then goes home and makes a rage filled video, which he then packages with pre-prepared materials to send to NBC News. Had the point been to send this package, he could easily have secured the complete address from his computer - but he chose instead to go to the Post Office and chance the wait in line to make sure than he was on record as having sent this damning evidence himself.

Then he returns to his 'work' in the classrooms. The lack of campus security, of campus video-tape, and apparently of more than one entrance to the building - then supposedly this combined to allow him to 'work' unmolested for an indeterminate amount of time. The amount of time involved was largely vague, due to police response time, but was probably triggered by cell phone calls from within the building. On the other hand perhaps some kind of rough reconstruction could be made from cell phone reports - as to which classrooms the calls had originated from, and during what time frame they were placed in?

If for instance reports were coming from two different rooms at the same time that shootings were underway - then again there would have been more than one shooter - but the police and other agencies would have total control over any such analysis.

Finally there were at least three photos being run by CNN - each one supposedly was accepted to be Cho. But the third image is completely different from the other two. He's wearing a light-blue open throat short-sleeved sweater - glasses on, a half-smile on his face ~ the image is a three-quarter view of the face, the head is slightly forward and gazing down. The other two were probably taken at very different times in his life which could account for some of the discrepancies - yet nothing explains the difference in his ears, or in the literal shape of both skulls, not to mention the cheekbone structure that is key to any actual id. However people will continue to differ greatly over this (counted on by the media - and one of the reasons they have stopped running the photos).

This one will probably never be solved to anyone's satisfaction, but then that's perfectly fine, if there is something to cover up. If not then it still speaks to how glaringly remiss all of the so-called security measures were and probably still are when it comes to actually protecting anyone from anything in real time - anywhere. (the whole premise behind HOMELAND SECURITY has always been that everyone can be protected) and anyone with a brain knows that this is simply not possible.

Just as a person must use layers of skill, with concentrated thought processes that could have been streamlined into automatic reactions: to do what Cho is alleged to have done by killing 32 people - it would not be possible for a shy, introverted young man to train himself to that extent, if he was operating on his own. The skills necessary would have made the owner of those skills very confident indeed - just as the absence of them would have contributed to his deepening anger and frustration. 

Briefly; skills of any type require more than just the particulars alone that anyone would seem to need.

A 'broken-field runner in football learns the components of that skill separately, and then gradually combines them so that when the skill is called on his reactions have become semi-automatic - because they don't need to be thought about - the memory that was ingrained in the training takes over and actually allows for the decisions necessary to take place on a level much higher than simple decision-making could ever allow for. All of this kind of training is inherent in taking on the kind of assignment that Cho supposedly set for himself. Also it should be remembered that his kill ratio was much higher than many experienced police officers could ever count on - from their own performances - either on the range or in the real life situation.

If Cho (or any combinations of him) had help in either the training or the execution of this heinous crime - then everything was and is still very possible. . .

I trained myself early on with portraits of ordinary people: over several years I probably did between 5000 and 7000 of these. Along the way, of necessity, the basics (the set of the eyes, the ear shape and placement, coupled with the spacing and size of the nose and lips) all of that became second nature and from that experience the two images here are definitely (for me) of two very different people. But hey - that's just my take. . . I summed up that experience in this illustration for "Something Wicked this Way Comes" for Ray Bradbury . . .  http://www.kirwanesque.com/special_projects/m_dark.htm
