thats the same old lame argument we have debated for years and could for the next 1000 years and the same argument could be made for guns.
but if steps are not taken to REDUCE the number of bullets a gun can hold or simple banning them all together we will never see a change in out countries gun probelms which are some of the worst in the history of the world!
have you ever used your gun in self defense? do you know anyone who has ever used their gun in self defense other then what you have read on the internet? I doubt you do!
I work with over 500 cops on a daily basis and NONE of them have ever used their gun outside of work. never once in 17 years and a lot of them live in the city which sees the highest crime rate in all of new england.
and not to mention I have only only seen on a handful of occassions any criminal having anymore then the standard magazine capacity so criminals with 30 round magazines may be popular in the movies

but in the REAL world its utter BS cause they are simply too hard to carry around and would be seen easily be LE.
