I'll just go one step further. The problem about making generalizations based on specific cases is we don't even seem to have people who care to get the primary facts right about those specific cases.
On the tragic death of Officer Pierzchala, reverse onus would fix this, except it was his bail review. It was already his onus, so reverse onus wouldn't fix that.
If we're really interested in fixing it, we need to look at some larger systemic issues. When you have someone who's out on a well-supervised bail, that could be monitored by the police, that could be supervised via a bail program that has the access to justice resources that allow check-ins and support. That is a perfect way—while someone is presumed innocent, mind you—to assist in the rehabilitation. This is because it can be supervised; it can be monitored.
Rest assured, from everything that we've seen in court, our courts take serious violent offence seriously. When we look at prolific offenders and people with long records, we see that that is taken very seriously. Bail is the perfect time to make sure people aren't set back; in fact, it's a time to help people take a step forward.
