Met Police Agent Provocateurs

[Jan Klimkowski]

He was known within the green campaign as Mark "Flash" Stone, having earned the nickname because he always seemed to have more money than the other activists.

Close reading the many articles on Kennedy (Stone), it's clear that: a) he was a frequent source of funding; b) this includes buying vehicles and other equipment used in protest operations. In other words, he was almost certainly providing material support to protest actitivies, some of which may have contained elements of illegality or criminality.

That makes Kennedy prima facie an agent provocateur:

agent provocateur French [aʒɑ̃ prɔvɔkatœr]
n pl agents provocateurs [aʒɑ̃ prɔvɔkatœr]
a secret agent employed to provoke suspected persons to commit illegal acts and so be discredited or liable to punishment

Below is an account from an activist who met Kennedy. It is clear that Kennedy's persona would have enouraged other protestors to brag of their own actions to further the cause, and perhaps even exaggerate or lie to curry favour with the undercover copper.

I came across Mark on a few occasions, at large gatherings and events. I have to admit, I never really liked him much, despite many others going on about what a great guy he was. He was a very macho man, always showing off his hardcore activist credentials and taking an atmosphere of bravado around with him. He seemed very attuned to informal hierarchies, seeming to seek out other Big Men and looking for the in-crowds. His big mouth instantly made me suspicious and guarded around him, not because I thought he was a cop, but just because I thought he was indiscrete.
Looking back, it's obvious to see that not only was Mark extremely good at making people trust him, his personality was perfect for getting tongues wagging. He was the kind of person who I can imagine encouraging others to brag about daring actions and someone who seemed like he'd be up for future ones.
