Domestic Terror Strikes

An American citizen, even a military veteran, might be persuaded by some foreign entity to stage an attack against his fellow Americans. This seems to be the case in New Orleans, where a turncoat murdered folks he did not even know, in service of world jihad. The local authorities could have made better preparation to stave off such an event, but failed to do enough to block vehicle traffic, permitting a traitor and fanatic to launch his killing spree. Not every terrorist assault can be prevented, but with proper defensive techniques, their evil attempts might be thwarted or the damage at least mitigated.
