The examples they cite are (1) military case in the Philippines (2) a police officer and (3) the knockout game of which they provide an example which doesn't fit the description they offer.
Then there is (4) the "scenario" the train for of four or five criminals attacking you.

1 and 2 are irrelevant, no one is talking about limiting military or police weapons. 3 and 4 don't support their argument, because as we all know, criminals are the first to get and carry guns. You know the slogan, if guns are illegal ... etc. So a 15 round tek-9 isn't going to do much against four gangbangers who also have tek-9s.
