A purse could be taken in broad daylight based on a true story. There are unfortunately many cases where thieves target people's bags, especially in busy public areas during the day.
An elderly person could be taken. Sometimes, scammers or criminals target the elderly who might be more vulnerable. They could be lured into a vehicle or a building under false pretenses during the day.
Some people freeze in shock. When a crime like a sudden assault happens in broad daylight, they are so stunned that they can't move or react immediately. For example, in a case where a person was mugged on a busy street, the victim just stood there for a few seconds before realizing what was going on.
One example could be a public protest. People gather in broad daylight to voice their opinions on various issues. It's a real - life event that is very visible and occurs during the day.
