I am having trouble understand why the klein-gordan eqn is accepted to describe spin 0 particles since it gives the wrong statistical interpretation (such as negative probablities).

Instead of trying to answer, I'll add another question without insinuating anything.

Why have we not observed any supposedly fundamental spin-0 particles in nature? :)

(higgs hasn't been observed)

The Klein-Gordan equation has to be second quantized to get to a QM wave function.
As a one particle equation, [tex]\psi^*\psi[/tex] relates to the charge density.
