Florida woman arrested for attempting to make a bomb inside Walmart using items from the store shelves

In Tampa, Florida, Emily Stallard, 37, was arrested for attempting to make a bomb inside a Walmart using materials she grabbed from the store shelves. From CNN:

"A security guard with Walmart noticed the woman ... roaming the aisles of the store and opening unpaid items. The items included flammable materials, projectiles and matches," the sheriff's office said...

"This woman had all the supplies she needed to cause mass destruction at her disposal," Sheriff Chad Chronister said.

"Had it not been for an alert off-duty law enforcement officer and a watchful security staff at Walmart, she may have followed through with her plans to cause an explosion inside the store..."

Stallard had a child with her at the time of the incident, authorities said. She was arrested on charges of attempted arson of a structure, fire bombing, contributing to the delinquency of a minor, child abuse and battery on a law enforcement officer. Deputies said she spit on them while she was being arrested.
