I live in a very "safe" area in an affluent suburb. However, we do have home invasions, car jackings, robberies, and the occasional drug related crime. When these crimes occur there are often multiple attackers as criminals are cowards and don't like resistance nor bad odds. You try to put rounds on target, effectively and make every one count in a life threatening situation with multiple attackers whom are also armed. See what happens. You will be glad you had a standard capacity magazine of 15 rounds or more in those situations. Why limit only the law abiding?
