The best defense for owning <10rd capacity magazines is that there is absolutely no guarantee that a violent attack can be brought to a halt with 10 rounds or less. If you need an example to use, consider that Michael Lee Platt had to be shot 12 times in order to bring his murderous rampage to an end during the 1986 Miami Dade shooting. Now, if one person, who was not under the influence of mind-altering chemicals, can require that many shots to stop them, how many might it take to stop someone who is drugged out of their mind or worse yet, a group of people with malice in their hearts? For someone trapped amidst the roving gangs that we saw during the Rodney King Riots or Hurrican Katrina, a "high capacity" magazine would be a very comforting thing to have.
