Note to prospective foreign eco-heroes who want to cause trouble in the US: If you'd like to avoid future Hassles By The Man, you might want to not try to super-glue your hand to the Prime Minister

Why This Prominent UK Enviro Caused a National Security Freakout | Mother Jones

Glass is a UK-based activist known for acts of civil disobedience as part of the environmental group Plane Stupid, which targets aviation emissions with colorful protests. He received international attention in July 2008 when he attempted to super-glue his hand to the jacket of then-Prime Minister Gordon Brown, an action meant to push Brown to pull his support for the Heathrow expansion. At the time, Brown was giving Glass an award for his environmental campaigning. The following year, Glass was one of nine climate campaigners arrested for occupying the tarmac at the Aberdeen, Scotland, airport in protest of a proposal to expand the airport to accommodate visitors to Donald Trump's planned golf resort.

Flashback: Campaigner 'glues himself to PM'

Speaking afterwards, Mr Glass said: "My left hand was covered in superglue and I stuck it to his sleeve.

"I just glued myself to him and after 20 seconds he tore my hand off - it really hurt. He had to give it a couple of tugs before it came away.

"He was just grinning about it. He didn't seem to take me seriously."

After the incident Mr Glass was allowed to stay Number 10 for 40 minutes.

When he left the building he tried to glue himself to the gates of Downing Street but was prevented from doing so by a police officer.

"I didn't have much glue left by that point," he said.
