Was this woman preparing to set off a nail bomb in her local Walmart? Security at the Florida store said they asked an off-duty officer to investigate after they observed a woman assembling what they suspected was a nail bomb. They saw her open a box of nails, put them in a mason jar, and start concocting a liquid mix. They swooped in when she seemed ready to detonate the device by setting fire to a shoelace. Shockingly, investigators say she used her son who was with her to help with the bomb.
