When will we realize that sadly, lone wolf attacks can occur anywhere in our nation?

The whole point of the lone wolf is that you don't realize them. Wolves are pack animals. A lone wolf attacking is something a victim will seldom ever anticipate. The issue of it is that you can't completely prevent every crime. Even if you knew they were there would you want all military personnel in the US to wear body armor and carry a rifle while in uniform? I don't think we didn't anticipate them. We did. But just as that lone wolf is you just about never see it coming.

And I think we we see more of these all too frequently.
