I actually think that vigorous enforcement of existing firearms laws would be a good thing.
The base problem is that gun banner types see that current laws "do not work" (and what law CAN work if it is not enforced?), and so constantly call for new more restrictive laws.
Personally, since we always have had laws that say you cannot shoot people for fun and profit, why do we need ANY gun control law?
Sadly, some people just cannot understand that people who break a high moral law will not obey any other law they consider inconvienient, either.
All else being equal (and it almost never is) bigger bullets tend to work better.
