Yes, certainly.
As the convoy travelled throughout the province, police officers were really absent the lawful justification to stop them at any point in time. There were no reasonable and probable grounds to identify any particular individual who was about to commit a criminal offence, which is a substantial threshold, as I'm sure Canadians would expect. Although there was lots of information on social media available, there was still the potential that it could be a lawful protest, so there were not lawful grounds for officers to stop the convoy at any point prior to it arriving in Ottawa and getting closer to the point of having reasonable probable grounds to believe a criminal act may be committed.
