Headscratchers / Angels Revenge

• Jim Backus and Alan Hale in the same movie, and not a single Gilligan's Island reference?^note At least not in the movie itself. The MST3K ep is full of them.
• As Tom points out... why can't they just buy ammunition? Are they just broke?
  • Maybe they don't want the weapons traced back to them. Stealing a cache of arms from a right-wing militia is less likely to gain unwanted attention than famous singer Michelle Wilson walking into a gun store and casually buying several boxes of grenades and bullets.
• Peter Lawford's character tells Jack Palance's character about "control" by using a Doberman as an example, stating that if he lost control of it for an instant, that the dog would tear him to shreds. In the climax, when the ladies lock Palance in, the dog attacks him. Wouldn't it have made more sense for Lawford to be the one killed by his own Doberman?
