Yet another school shooting tragedy in the USA. More families left grieving for their loved ones.

But am I right in believing that all schools are now in what they call "gun-free zones"?
If so, this policy is surely another example of loony lefties enacting laws that may look good on paper, but in practical terms don't make sense.
A "gun-free zone" means a gunman is free to kill until he's confronted - eventually - by police with guns! Lunacy!
