Camouflage - not what it seems?

Newsnight just showed footage of a transit station, where the Israeli army screen goods due to be imported to the Gaza strip - humanitarian aid. A soldier showed us "contraband" that they'd discovered in the aid shipment. What was it? Camouflage trousers. "Waterproof uniforms", apparently. Two pairs of trousers in amongst several tons of what could simply be second hand clothing. Not impressed! I'm sure that they'd have shown us something interesting if they could find it. This set me in mind of Colin Powell's devastating evidence of WMD - a satellite photo of a truck parked outside a building.
