Are the president's kids more important than yours?

Yes. 

I'm sorry, was there some confusion over that? I mean, his kids aren't more important to him than your kids are to you, of course. But they're more important in terms of national security, because when the president's kids are threatened it impinges on his ability to do his job - which puts America's security at risk.

That's why Congress requires that the Secret Service protect not just the president, but his family. The president couldn't turn down Secret Service protection if he wanted to.

That's another thing - those "armed guards" who protect the Obama daughters when they're at school are not employed by the school. (They go to a Quaker school, which - if it's anything like the Quaker college where I worked for four years - doesn't have armed security, period.) Those "armed guards" are insanely-highly trained Secret Service agents who guard the girls at school and anywhere else they go. Because federal law.

The NRA is all concerned about hypocrisy now? Okay. When the armed personnel you want in every school in America have to undergo the selection process, the background checks, the training and all of the other weeding-out that those agents go through in order to have the privilege of watching the president's kids, then we can talk.
