If we use the analogy of a bar fight. There is an ongoing brawl between two partues. One of the combatants is for reasons now jabbing punches at another person in the pub. Perhaps pre-emtively in case they might think of helping out the other guy. The other drinkers nearest the brawl have their own views, to be determined. The self proclaimed bouncers from the bar next door, but with interests here too, have made some supportive comments. Will these bouncers be wanting to enter this bar, at this time and either cool things down all round, or mind the back of their pal. Most people just want to get on with their own thing but worry that they’ll be caught up in a brawl.
