You probably want to scope this to only letting the creator of the review or an admin delete this:

```ruby
def destroy
  if current_user.is_admin?
    review = Review.find(params[:id])
  else
    review = current_user.reviews.find(params[:id]) # limits the scope to reviews made by the user
  end

  food_truck = review.food_truck
  review.destroy
  redirect_to food_truck
end
```
