For nearly two weeks anti-vaccine mandate demonstrators and their big rigs have entrenched themselves in Ottawa's parliamentary district and its neighbourhoods.
Despite a strategic strike by police to cut off supplies to truckers encamped in the city's downtown core, protesters appear to still have the upper hand on police.
It's a success that experts partly attribute to the deep knowledge of law enforcement and military tactics that exist in the convoy's organizational structure.
The group Police on Guard, formed during the pandemic, has endorsed the truck convoy. On its website, it publicly identifies more than 150 mostly retired police officers who are against government-imposed public health measures, such as vaccine mandates. More than 50 former Canadian Forces soldiers are also named on its site.
The organization says it has "boots on the ground" in Ottawa and has linked to YouTube videos of its members participating in the protest.
Furthermore, the leadership team for the protesters calling themselves the Freedom Convoy includes:
Daniel Bulford, a former RCMP officer who was on the prime minister's security detail. He quit last year after refusing to get the vaccine and is the convoy's head of security.
Tom Quiggin, a former military intelligence officer who also worked with the RCMP and was considered one of the country's top counter-terrorism experts.
Tom Marazzo, an ex-military officer who, according to his LinkedIn profile, served in the Canadian Forces for 25 years and now works as a freelance software developer.
