it's laughable, because even cops aren't this stupid --
I almost want to save this movie as example of the dumbest, most implausibile movie ever (but there may be a couple others).
For example, in the first 10 minutes, when the cop addresses the guy who survived the major car wreck, walking toward the cop with his hand in his pocket, the cop deserved to die, because he was not following standard rules of engagement.
Then, the owner of the gym, who seemed to be over 200 pounds, wacked the guy with a baseball bat 3 times in the groin and 3 times in the head... but since the guy apparently had superhuman strength, he was able to kill him with one punch...
It all got even dumber after this, but this actually provided some short-term, laughable entertainment.
