No, I go See a few non league sides here in Essex and Kent. Apart from Southend Utd with no Trouble, There has been incidents at all the others. The last one I went to Bowers and Pitsea, Paul Hayes is there (ex PNE, now director of football) Both teams and officials got into a punch up, spills into the crowd of about 100. I just sat and watch with a little snigger. Challenge was nasty, but Referee gave the Freekick the other way and the Yellow, all hell broke loose. No Stewards so it was left to fizzle out. No cards for the fight, I think the Ref bottled it. So my experience. there is more trouble at Non League games. Southend still has Stewards, the most you get is a crowd surge and argument. But they have to get up and past people. To much effort, hence no issues.
