The shootout took place in 2008, but the details are just coming out. PoliceMag.com has the full story:

Maddox point-fired at Gramins as he charged toward the patrol unit. Four bullets hit the front of Gramins’ squad car.

Gramins let loose with a barrage of rounds hoping that what he might lose in accuracy would be compensated for by its suppressive nature. The only thing separating Gramins and his assailant was a windshield that was fast disintegrating from ingoing and outgoing rounds.
