People that kill others out of Gross negligence often go to Jail but regular negligence I’m pretty sure isn’t criminal, though I’m not Canadian. I’m the other kind of American.
Gross Negligence per Wikipedia is a “lack of slight diligence or care” or “a conscious, voluntary act or omission in reckless disregard of a legal duty and of the consequences to another party.”
Not likely. Trump doesn’t even know what those words mean. Temporarily jailing them and protesters is likely a different story, though.
