Ah, but they were wearing a bright yellow vest! Be honest - would you think twice if you saw someone wearing a safety yellow vest and carrying a drill? Apparently there was construction going on nearby as well, so the basket lift didn’t really stand out.
True, but that still begs the question, why were they filming that person if they didn’t think something was going on? Not that I’d expect a bystander to throw themselves upon a thief, but interesting they still got away after being noticed and filmed during.
Maybe the person wasn’t sure but suspected something so better catch it on camera just in case. These thieves were fast so don’t expect random bystanders to react as you would with some time to think.
