Somewhere in a DHS storage facility is the round that will likely end my life.

Or at some hotel is the bath tube you might slip in and break your neck....
Death is still far to random to pin it down to a bullet in a DHS warehouse.
Go with the statistics and probabilities first. A single bullet in the DHS warehouse is far outside of the likely hood of your demise. There is also the brown recluse spider under your bed who is probably on the higher probability list too.
Sleep good....
