Came across a street disturbance

Having just been to the cinema and watched the ridiculous and gory at times film The Mechanic, I was driving home and came across a street fight/brawl in the north inner city of Dublin.

I'll tell ya, I was sh1tting myself for a few seconds as the participants who were mostly women(egged on by male teenagers) started to wander towards the car for a small bit while belting each other. Had to reverse the car to avoid them. Didn't want the epitaph on my grave to have been 'lynched by the Pyjama brigade'.:);)
Ironically the Kaiser Chiefs song I Predict a Riot was on the radio when I met this crowd, what are the frigging odds of that?

And yes, those of you that know me will know I had caught all 30seconds of it on camera in the car. I didn't hang around to know what happened, I did call the Gardai when it was safe to pull over a few streets down. After about 5mins, the blue lights screamed passed me, fair play there.

If you came across something like it, what would you the brave AH brigade have done?

1 - Get out of dodge asap
2 - Hang around and enjoy the spectacle
3 - Stay my ground keyboard warrior style and run them over?
