Which aspect of it do you think will lead to a reduction in crime?
All aspects. The harder it is to procure a powerful gun, the less likely that it will be used to commit a crime.Do you know how many people in Maryland were murdered by someone using one of these "powerful guns"? 2. That is, two. Do you know how many were murdered with hands and feet? 17 ALMOST NINE TIMES AS MANY! How about knives? 75!
Then why not make it 8? or 3? Do you know how long it takes to reload a magazine? Not very. Do you know how many people are killed by that 11th and 12th round in 12 round magazines? I don't, but I bet it's pretty freaking small.
Indeed a couple of those might actually do something to slow down crime (that is already awfully slow), but banning rifles of any kind is as stupid as invading Iraq after a bunch of Saudis flew planes into buildings.
Of course you do, you know it won't help much, but hey, we've got to do something!
