As much as I disagree with the convoy movement, it seems that the charges are more politically motivated (anti-far right) than bringing justice. A lot of those charges could be applied to anyone partaking in a protest: mischief, obstructing police, and intimidation are all charges that could potentially be applied to both the convoy and the current ceasefire protesters at various North American campuses; given a literal reading of the criminal code.
besets or watches the place where that person resides, works, carries on business or happens to be;
(b) renders property dangerous, useless, inoperative or ineffective;
Offenses related to public officers:
(a) resists or wilfully obstructs a public officer or peace officer in the execution of his duty or any person lawfully acting in aid of such an officer,
Obviously there's a double standard where such charges would not even be brought up unless it's extreme cases. But shall pat King be charged and given a lengthy prison sentence (5 years for example), that'd probably set a precedence for the justice system to be used to deter politically motivated protests; this time it's the freedom convoy, the next could be Gaza-related protests shall it persist.
