Because the device is dead or damaged. “As for the effect after being soaked in water, for example. Is there a difference in the effect of the device that is only turned off with those soaked in water?” Ask the prosecutor. “There should be no difference,” Bob replied. “But the position of the device can no longer be monitored?” Ask the prosecutor. “Yes,” Bob replied.
