"But he had seen a study saying that 30 percent to 40 percent of slain police officers had been killed with high-capacity magazines."
That statistic
alone should be enough to spur Congress to act on magazine/clip limits. My preference would be to see a 7-round limit on magazines for all civilian semi-automatic pistols - that's still one more shot than the average revolver, and if it is true, as our "pro gun progressives"* are constantly assuring us, that such a limit would "make no difference" then there should be no opposition to limiting them to that number from any quarter. After all, why oppose something that's going to make "no difference"?
The answer: it
will make a difference, which is why the NRA shills & sycophants oppose it so loudly.
In any event, I doubt we could ever get seven but a lot of us would settle for a ten round limit along the lines of the 1994 law. As it looks like both magazine limits and a new AWB has stalled in the Senate this session, it's looking like it will depend on the next session of Congress to get this necessary work done.
