The far-fetched scenario of a government grappling a zombielike threat — think movies like “Night of the Living Dead” or, more comically, “Zombieland” — has captured the attention and imagination of Brad Barker, president of the security firm HALO Corp.

Next month, his outfit will incorporate — no kidding — zombies into a disaster-crisis scenario at the company’s annual Counter-Terrorism Summit in San Diego, a five-day event providing hands-on training, realistic demonstrations, lectures and classes geared to more than 1,000 military personnel, law enforcement officials, medical experts, and state and federal government workers…

The zombies who roam the island will harass the troops, first-aid teams and medical responders participating, Barker said. HALO declined to detail the scenario just yet, saying only that the idea is to challenge authorities as they respond to extreme medical situations where people become crazed and violent, creating widespread fear and disorder.
