Humorous Airport DoS (from cryptogram)

For example, airports have dogs and devices for detecting the chemical emissions from explosives. If I took a small perfume sprayer and filled it with nitrobenzene (used in firearm bore cleaning solvents) and sprayed people's luggage with it as they awaited security screening, the airport would soon be shut down due to the threat perceived by security. Or if I sprayed the seats in the airports lounge or restaurant, the bomb-sniffing dogs would become butt-sniffing dogs, to the major embarrassment of security. This last, while humorous, would go a long way toward discrediting the security force.
