ABC News reports that the Virginia Tech killer apparently acquired both of his weapons quite recently and perfectly legally.

Cho Seung-Hui bought his first gun, a 9 mm handgun, on March 13 and his second weapon, a 22 caliber handgun, within the last week, law enforcement officials tell ABCNews.com.

“This was no spur of the moment crime. He’s been thinking about this since at least the time he bought the first gun,” said former FBI agent Brad Garrett, an ABC News consultant.

Both guns were bought in Virginia, according to the officials.

Under Virginia law, state residents can only buy one handgun in any 30 day period, suggesting Cho bought his second weapon after April 13, or sometime over the weekend.

“He clearly spent some time figuring out how he was going to take care of business once classes began on Monday morning,” said Garrett.

The date of the first gun purchase will likely serve as the time of “some triggering mechanism that was very important” to Cho said Garrett, an expert on profiling murderers.

There is still a great deal needing to be explained about all this.

Neither a 9mm nor a .22 represent the last word in lethality. So how is it possible for one 23-year-old student to shoot 47 people and actually kill 32 (totals from latest NY Times report)?

in 1999, four highly trained plainclothes members of an elite New York City crime squad fired 41 shots at Amadou Diallo hitting him with only 19 shots, most of which were not considered lethal by the coroner.

In another New York City shooting incident, this February, five police officers opened fire on Sean Bell who was driving away from his bachelor party. They fired 50 rounds and struck Bell only 4 times, although two passengers (who survived!) were hit respectively 4 times and 16 times by police fire.

So, how is that a 23-year-old Korean college student was able to so dramatically outperform police professionals in accomplishing lethal hits on human targets? He was obviously not using any more potent, or more intrinsically accurate, a weapon.

He apparently bought his first gun on March 13th. Where did he acquire such shooting skills?

Or is it possible that roughly 30 people obediently lined up and just stood there, so that one man could shoot them all in the back of the neck execution-style? I’d hate to think that was what happened.
