You aren’t wrong actually, I made a post a yesterday I believe which Criminal Defence attorney Jordana Goldlist explains that self defence in Canada occurs at trial, people who justifiably defend themselves and are arrested have to essentially sit in legal limbo waiting for a judge or jury to determine their outcome which really isn’t fair for the victim given they’re forced to relive the moments of the event.
If the person defending themselves went way out of line I absolutely agree they should be prosecuted however, there needs to be some change in the system that doesn’t immediately criminalize the victim.
