Every politician wannabe reads The Prince by Niccolo Machiavelli at some point, and Trudeau obviously didn't pay attention. Machiavelli clearly states several times, that if you're going to kill a bunch of your citizens, you have to kill them all at once and then immediately promise the surviving population that the purges are over. If you kill them in smaller groups, it's going to take a lot longer, and the population will get so anxious because they're afraid they might be next, they're just gonna say Fuck It and come after you with everything they've got.
Not finishing the protests was a mistake, but the freezing bank accounts is the actual REAL mistake. Trudeau is forcing the entire country to wonder if they might be next to get their money shut off, and this is the modern equivalent of being executed. Freeland just said that they're going to make this law permanent, and even the BLM supporters are now screaming WTF because any idiot can see that this tactic will be used on the next group and the next group and so on, etc.
