When Tommy is fighting in the garage just after the car flips over, a guy in a van gets s dirty great machine gun out of the back of the van! It's belt fed, you clearly see the belt has nearly expired when hundreds more bullets come and the belt gets longer!!.
When Tommy parks the motorcycle to make a phone call to Big Doug, he parks in front of a car with a Washington State license plate number PHF-654. When Tommy drives off in the truck at the end of the movie, the truck has the same license plate.
When Tommy shoots Monique, her reaction is obviously unrealistic and out of sync. Even though he fires more than a dozen bullets at her, this only causes Monique to stop propping her head up with her elbow while lying still. Then, only after Tommy stops shooting, Monique twitches a bit. Furthermore, being shot so many times would cause her corpse to be completely disfigured from all the gunshot wounds, yet once the debris and smoke settle down it is obvious that Monique's body does not have a single wound.
