It's rare to see so much aggression in a town centre on a Saturday before midday.
Yet somehow a derby game between the old foes Southampton and Portsmouth provided an excuse for a few individuals to take to the streets looking for trouble.
If I'm honest, I still don't really understand it. I've heard people tell stories of rivalries between dockworkers on the two coastal towns that go back generations.
But so what? What relevance does that have today and, in the end, how can anyone justify some of the hatred and abuse witnessed on Saturday.
In one instance a young lad, probably about eight years old, wearing his team colours on the way to the ground with his dad was spat at and verbally abused in the most horrible way.
It's not even that I'm easily offended. As a football fan I really enjoy a bit of rivalry and healthy banter at games.
And far from oozing tribal hatred, in my experience the genuine fans often come up with some pretty funny stuff. For some reason, I'll always remember Chelsea fans taunting a losing Norwich City team (where Delia Smith is majority shareholder) with the chant: "you're going down with the soufflé, down with the soufflé..."
The vitriol and irrational hatred just comes from people who want the adrenaline rush of a fight. The football itself is an irrelevant excuse.
So how do you police those idiots when the majority of Saturday's sell out crowd just wanted to watch football?
I'd be keen to hear your thoughts. With police horses, dogs and 270 officers on the streets I've heard one or two people say they thought the law was too heavy handed.
And yet those resources seemed very justified as trouble flared up at two key moments either side of the game.
There were a few close calls and yes at times the thin blue line was probably stretched a bit too thin as groups of Southampton lads seemed to come at their contained rivals from nearly every side.
But the police seemed to keep their nerve. Instead of banging heads together some of the offenders caught on CCTV before the game were located during the match then quietly arrested, minimising confrontations between fans and police.
And now hopefully the police can go back through all the other evidence they gathered on the day and make more arrests.
Only then, with banning orders in place do the real fans and families have a chance of following their side without the distant threat of violence or intimidation.
