What if your employer tied you and covered your mouth with duct tape?

Today, I was a little surprised to learn that NASA has developed a policy for how to deal with a psychotic astronaut. NASA's policy involves the use of force, through binding an individual's ankles and wrists together, and then injecting that individual with tranquilizers. Granted, the policy only applies to potential problems that arise while in space, but imagine if that policy were applied in an everyday workplace? Instead of a calling security for unstable behavior, an employee was tied up and shot with tranquilizers. This new policy by NASA determines on a case-by-case basis whether such action is necessary, depending on the severity of an astronaut's psychosis. This policy has recently been instituted because of the incident that occurred several weeks ago where one astronaut attempted to murder another because of a heated battle over the affection of another NASA employee. While I commend NASA for thinking of a new "what if" scenario, I have to wonder if this is the best policy to manage an unstable individual in space? I would think that involving physical restraint would place a crew in more danger than necessary. Do you think that there is a less restrictive way to make space safe if such an incident occurred? Focusing more on the impact of the employer-employee relationship, do you think that enforcing any organization's policy on a case-by-case basis is a good idea? What are some pros and cons? Who should be the one to make the decision that the policy needs to be enforced? How would you eliminate bias from this process?
