You'd be surprised how it actually unfolds in court in terms of innocent until proven guilty beyond a reasonable doubt.
The Crown will connect the tiktok account to the individual via IP etc., they will then show that said individual owns the bike in the video. The onus is then on the accused to provide evidence it wasn't him. And that evidence would need to create a "reasonable" doubt...
Ultimately, there is no onus to PROVE it was he that is riding. Just evidence to the lead to that.
You don't know what you're talking about
The onus is on the crown to prove their case... not the accused to prove their innocence.
The video is almost useless without some corroborating evidence.
My guess the accused admitted it was them riding the bike
