I loved the gameplay. Being a cop (dirty or good) was a load of fun, fun that is utterly destroyed by the freezes, glitches, and bugs. It seems the developer didn't even finish the game. You better avoid this one.
If framerate problems doesn't annoy you, then the stupidity of the A.I. may force you to say, "that sh*t is wow, bananas." Enemies are stricken by stupidity, as they'll simply stand there and allow you shoot the living daylights out of them.
