Welch, who told authorities he went to the establishment to “self-investigate” the sex ring claims, allegedly was spotted looking for rumored tunnels filled with hidden children...

A ground-penetrating radar unit would have been a better tool than a rifle for that purpose...

The guy shoots into the floor because he believes there might be tunnels full of kidnapped children...under the floor. Is he a:
1) dangerous moron from the Tinfoil Planet;
2) false flag operator;
3) recipient of the same training that led federal LE to burn down the Branch Davidian compound to help the children inside.

(I’m going with #1.)
