Look here on the OSHA Site. They show some similar situations, and they make similar statements.

If the ungrounded (hot) conductor goes directly to the motor, and the grounded (neutral) conductor is wired to the switch, and then the right hand side (in the drawing) motor lead faults to ground, the drill will operate independent of the switch and start as soon as it is plugged in.
I'm confused as to the problem here...
Help me, please!

ACCIDENT 5 on the "High Impact Electrical Safety Video" shows:

Ignorance of Proper Tool Grounding Results in Death

Jarvis Bunt decided to repair an extension cord that he and Alvin Potter had run over with their forklift.

Jarvis found a new end piece and put it on the cord, but was not aware that the wires must be connected to specific terminals. He connected the hot wire to the ground terminal. When Alvin used the cord to power
a skill saw about 30 minutes later, he was electrocuted and the saw blade buried in his leg.

SAFETY TIPS: You must be qualified to do any electrical job. Jarvis was not qualified to repair the cord. He did not understand why each of the three wires must be connected to a specific terminal.
