So you did want armed security guards in all the schools but now you want armed parents in the schools? Maybe armed children?
No, it's very simple, let me explain it so that even a democrat should be able to understand it:
Picture anywhere that keeps valuable things. What do they have?
- Controlled entry to where the things are kept
- Someone on guard at the entry
Have those things for kids, because they are valuable.
In this case, the doors were open, no one was on guard and the gunman walked right in.
The police then actively prevented anyone else taking action, handcuffing and tasering them, while the gunman executed the kids.
