Terrible policing right from the time of the incident through to the trial.
It's ridiculous in the first place that plain clothes officers will bang on someone's car like lunatics and expect someone to comply with them, especially in a neighbourhood where apparently stabbings occur. If they are in plain clothes, unless they actually see a crime happen, they shouldn't be able to arrest a bystander. That scenario has misunderstandings, accidents, and potential violence escalation written all over it. It's crazy that all they have to do is say they are the police and expect people to automatically comply, which apparently is the case even if they are in plain clothes, but why would anyone want to risk it? It's good that the police are being exposed for this, including what happened after the incident.
This isn't the first time that plain clothed officers ended up creating a far more dangerous situation than what was called for. Some jurisdictions don't allow it anymore for that reason.
Same thing with police in unmarked vehicles, which is the same principle. Like this case that happened in Edmonton last year:
