Considering the entire thread was about adding bullet proof walls to classrooms to protect children, I fail to see how medical school comes into play.
If we're talking about adding security measures to schools to protect our kids (who some of you were keen to insist are our future) then why would we suddenly jump to adults in medical school who are in their 20s?
Seems to me that El Pres was talking about k-12 because that's actually in line with what the original topic was about, and it was you guys who decided to go off topic to try to prove a point
