Is it feck, it is anything but "normal behavior" imo. I don't want to be associated with these morons who can't behave properly, regardless of what they're celebrating. Attacking an ambulance is a major no-no even in regular times, let alone during this pandemic. How sick, or blind drunk, or morally apprehensive (or all three combined) do you have to be to do such a thing? I don't have any time for these "fans", it's literally the most egocentric thing you could be doing right now and basically giving the finger to the NHS, people at risk, your own grandparents, you name it.
It genuinely thought the majority of the fans living in and around Liverpool would be smarter than that, and maybe the people in those videos are just a very tiny minority of our actual fanbase and 90% did actually behave, don't know, but it's a stain on our title win as far as I'm concerned. There are enough other ways to celebrate this.
