NEW YORK (Reuters) - Travellers passing through New York's John F. Kennedy International Airport this week witnessed a show of force following the Brussels airport attack: U.S. Army soldiers in khaki camouflage bearing assault rifles, police officers in black bullet-proof vests and private security guards directing traffic in neon-yellow vests.
The variety of uniforms is a sign of the overlapping jurisdictions that determine which federal, state or local agency - or even airline - is responsible for security on any particular patch of turf. That could make sweeping security changes at JFK or other major U.S. airports difficult in the wake of the deadly Brussels attack.
