Evan Booth, who calls himself an "independent security researcher," recently posted some videos on YouTube that show how he was able to create weapons from items that are normally available at airport gift shops, after passengers have gone through TSA security screenings.
On his website TerminalCornucopia.com, Booth writes:
As it turns out, even a marginally “MacGyver-esque” attacker can breeze through terminal gift shops, restaurants, magazine stands and duty-free shops to find everything needed to wage war on an airplane.
Booth also raises the question "What if terrorists see this?" and answers:
What if they already know all this? All of these findings have been reported to the Department of Homeland Security (TSA) to help them better detect these types of threats. Furthermore, the next time you fly, you’ll be flying as a more informed consumer (and taxpayer, possibly) — one who is more equipped to demand better, more appropriate airport security.
According to Infowars.com, one of Booth's explosives, the "FRAGGuccino," was built out of a stainless steel coffee mug, AA lithium battery, condom, Axe Body Spray, water and a magazine (video below).
