I didn't say who was doing the speculating, just that it was speculating
But your posts heavily imply it was the reporter. Don't forget you started out by claiming the reporting was odd. Then I asked what was odd about it and you started talking about the speculation. Can you see why I assumed you meant the reporter was speculating?
and yes, I get what it might mean but it's still odd. Is the suggestion that they are upset with social distancing?
In less turbulent times I would speculate that the police chief meant that the mob was alcohol fuelled by clubbing and partying.
