Yes, businesses should face much more severe penalties if they are found to be employing criminals who regularly participate in high-tech crime, because the businesses know that they are employing criminals, and they look the other way. The businesses can help defend against this if they have an incentive to.
It is partly the responsibility of the employer here in the United States of America along with the rest of the world to make sure such events do not take place. The employer should have a better watch over the people that they hire and also what is going on.
If a business knowingly harbors high-tech criminals, they should be severely punished. Much like the Taliban harbored Osama bin Laden, there is no excuse for companies to knowingly have criminals on staff. Companies that willingly hire illegal immigrants should also face stiff penalties because they take away from American jobs who should legally have them. All of these scenarios are just about equal in scope because they can drastically affect American lives on a regular basis.
Businesses should not be responsible for employees actions outside of their job and laws should penalize businesses for employing someone. People who participate in high-tech crime can continue on without their employer knowing about it and employers shouldn't have any reason to pry into an employees personal life. To say they are somehow at fault or should be penalized is highly unfair. It also puts too much power in the employers hands.
