H/t Riehl World View. New reports state that the two suspects at Goose Creek also had bullets:

TAMPA — Bullets were among the items investigators found in the car of two University of South Florida students.

The deputy who pulled over Ahmed Abdellatif Sherif Mohamed and Youssef Samir Megahed, 21, found a box of bullets near the seat, several pipe bombs in the trunk and “other suspicious items,” according to the Berkeley County Sheriff’s Office.

The men have said they had only fireworks, but deputies found no sign of any commercial fireworks, said Berkeley County Chief Deputy C.W. Henerey.

Hmm. What were two Arab Floridian students doing driving late at night through South Carolina, near a military base, with ammunition, pipe bombs, and an open laptop (which they quickly shut)?
