  A de Broglie-Bohm like model of Klein-Gordon equation, that leads to the
correct Schrodinger equation in the low-speed limit, is presented. Under this
theoretical framework, that affords an interpretation of the quantum potential,
the main assumption of the de Broglie-Bohm interpretation--that the local
momentum of particles is given by the gradient of the phase of the wave
function--is not but approximately correct. Also, the number of particles is
not locally conserved. Furthermore, the representation of physical systems
through wave functions wont be complete.
