I believe that they advertise it as nano coated splash resistant. So, if you're caught in a rainstorm or carry it in your pocket while you exercise and sweat, the phone should be fine. A soaking, though. Not so much.
If you set up android device manager or Motorola's remote management facility, if the phone boots without the screen working you'd be able to do a remote data wipe. Or you can try a remote data wipe so that the next time it powers on it will be wiped.
