Kabul, Afghanistan (CNN) -- The guard who killed the half-brother of Afghan President Hamid Karzai, had for years worked with International Security Assistance Forces against Taliban militants, according to three local officials with direct knowledge of the dealings.

Sardar Mohammed, who authorities say shot and killed Kandahar's provincial council chief Ahmed Wali Karzai, received training from ISAF and participated in intelligence gathering against militants across the region, according to Besmellah Afghanmal, a provincial council member with close ties to the Karzai family.

He "was one of the trusted commanders for the Karzais," Afghanmal told CNN. "Sardar Mohammad was working with American Special Forces closely and he was participating in many operations with American Special forces against the Taliban in (the) south."

Others, like provincial parliament member Hashim Watanwal, say Mohammad had worked with both U.S. and Canadian forces in Kandahar -- an ethnically Pashtun dominated region long-considered the Taliban heartland.

Baz Mohammed, a Kandahar tribal elder with close connections to the Karzai clan, said the guard was "a trustworthy person" who collaborated regularly with ISAF in Kandahar.

An ISAF spokeswoman declined to comment on the claims.

Though suspected of corruption and opium dealing, Wali Karzai was considered a major power-broker in Afghanistan's restive south and a bulwark for his brother against the Taliban militancy.

His death Tuesday sent shock-waves across Afghanistan's political landscape, and prompted President Karzai to weep as mourners gathered for his half-brother's burial the following day.

Saidkhan Khakrezwal, a member of the Kandahar provincial council, said he and others were with Wali Karzai when the guard came into the room and asked to talk to him.

Las Vegas (CNN) -- For David Shafter, it should have been a dream: A crush of excited people swarming his booth at the International Consumer Electronics Show, where his startup is launching its first product.

But all the people hoisting cameras and raising themselves on tiptoe for a better view Wednesday afternoon weren't there to see his robot. They were angling for a peek at pop star Justin Bieber, who was making an appearance at the booth next door.

"We're pretty much shut down," said Shafter with a weary look of resignation, as rubberneckers squealed and shouted "Justin!" in the background. "We can't run our demos."

Shafter's fledgling company, Xybotyx, is making its first appearance at CES to introduce its Xybot, a hockey-puck-shaped robotic device that zips around on little wheels, controlled by an iPhone or iPod Touch.

Owners can download apps to their phone that give the robot specific behaviors, like avoiding obstacles. The gadget will go on sale this spring at the quirky price of $111.11.

But none of the hundreds of people pressed up against his booth cared about that.

They only had eyes for the teen singer with the sideswept hair who was greeting fans nearby at the TOSY booth, where he made an appearance on behalf of that company's new mRobo, a portable speaker that morphs, "Transformers" style, into a little dancing robot.

Middle-aged tech execs aren't exactly Bieber's demographic, but many onlookers said they were there to get photos or autographs for their teen-age kids. Some people even asked if they could climb atop Shafter's plywood demo table to get a better view. (The answer was no.)

Answer the questions at the end based on the text.

There seems to be a general assumption that brilliant people cannot stand routine ; that they need a varied , exciting life in order to do their best . It is also assumed that dull people are particularly suited for dull work . We are told that the reason the present-day young complain so loudly about the dullness of jobs is that they are better educated and brighter than the young of the past .

Actually , there is no evidence that people who achieve a lot desire , let alone live , colorful lives . The opposite is nearer the truth . Einstein worked out his theory of relativity while serving as a clerk in a Swiss patent office . Immanuel Kant's daily life was a dull routine . The housewives of Konigsberg set their clocks when they saw him pass , on his way to the university . He took the same walk each morning , rain or shine . The greatest distance Kant ever traveled was sixty miles from Konigsberg .

It may be true that work on the assembly line dulls the abilities and empties the mind , and the cure is only fewer hours of work at higher pay . But during fifty years as a workingman , I have found dull routine coexisting with an active mind . While doing dull , repetitive work by the water , I could talk with my partners and compose sentences in my mind , all at the same time . Chances are that had my work been too interesting I could not have done any thinking and composing at work or even on my own time after returning from work .

People who find dull jobs unbearable are often dull people who do not know what to do with themselves at leisure . Children and mature people will get used to dull routine , while the adolescent , who has lost the child's ability for concentration and is without the inner resources of the mature , needs excitement and novelty to get rid of boredom .
