Electrocution

We use it to execute killers. Now, apparently, we use it to kill our own soldiers. According to CNN:

A highly decorated Green Beret, Staff Sgt. Ryan Maseth died a painful death in Iraq this year. He died not on the battlefield. He died in what should have been one of the safest spots in Iraq: on a U.S. base, in his bathroom.Ryan Maseth, a 24-year-old Green Beret, died in his shower January 2. The water pump was not properly grounded, and when he turned on the shower, a jolt of electricity shot through his body and electrocuted him ... In a statement to CNN, the U.S. Department of Defense said it "considers this to be a serious issue and has referred it to the DoD Inspector General's office for action."

The Defense Contract Management Agency declined to answer CNN's questions.

Can anyone give me a good reason why trusting the Army on this would be a good idea?
