In this kind of scenario where no one is shooting back magazine size doesn't make much odds - taping 30 round mags together wouldn't have really slowed him up. Restrict to like 5-10 round mags or having to load a round between shots and he would have likely gone for a sniper type rifle and done the old bell/clock tower thing instead.
very true...but it would certainly have reduced the number of injuries and very probably deaths
if you cant stop people owning guns, authorities should at least try to mitigate the number of people that can be killed or injured in the response time of the police
