I don't. I don't want people writing laws who don't know anything about, or are unwilling to obtain even the meagerest of understanding of what they are writing laws for. It is absurd.
As for hollow point bullets.
They are widely used in law enforcement and for self defense for two reasons.
1. They are designed to expand when they enter the body. This creates more "stopping ability" simply by creating more damage.
2. The expansion greatly reduces the chance that the bullet will exit the body and continue on to due additional damage to other who may be in its path. It is safer for bystanders. This is a great advantage in law enforcement. It is also helpful for civilians who are probably not as trained as laws enforcement is.
Now, in relation to assault weapons and the horrible incident in Newton. Those were not hollow point rounds. They were relatively small caliber but high power. And there were a lot of them. And the muzzle velocity out of that Bushmaster was a lot higher than anything any hollow point coming out of a pistol.
I understand that we want to do something. But I cringe when I hear factually incorrect statements about this or that aspect of firearms, and then a cry to base legislation on it. That's crazy stuff.
I am not an expert. But I do have some basic understanding. I expect lawmakers to as well. What is the point of passing laws that address fantasies? They will be a dismal failure and all this momentum will have been lost.
one edit: I am not an expert on armor piercing ammunition, but I do feel that armor piercing rounds would likely pass through a human body with far less damage than a hollow point or a standard target round. Armor piercing rounds are designed to penetrate and some even get sharper as they go through armor. This would probably produce a cleaner wound but it would exit the body having hardly slowed down and proceed to strike something or someone else.
