DAVID HOGG: Sadly, my sister, she's a freshman, and she had two of her best friends die. And that's not acceptable. That is something that we should not let happen in this country, especially when we're going to school. It's something that we really need to take a look at. The fact that this is the 18th school shooting and this is only February is a testament to where this country has come and how far we need to -- we need to dig out of this hole. We need to step out of it and take a look back and realize there's something seriously wrong here. And some of our policymakers and some people need to look in -- they need to look in the mirror and take some action because ideas are great, but without action ideas stay ideas, and children die.
