While you are correct, no need for violence at all, though tv interviews and radio phone ins with genuine supporters not involved in the violence were people just wanting a football club back, which few are now in the premiership.
They are playthings and money makers for those with plenty of it anyway, Asset stripping and running up debt is par for the course, usually to fill their coffers more.
The super league announcement was badly timed, towards the ending of restrictions with people desperate to get out, and has backfired badly. Supporters are reacting against these billionaire club owners and have realized for years that football is being ruined by their greed, this was the final straw and has motivated genuine supporters to group and react, thugs have no place in that, but the seed is sown.
West Ham, now homeless and renting is a case in point, where has the money gone from the sale of Upton Park? You cannot tell me the board spent it on players, or that they were not involved in building the housing estate now there, making more money and it was blatant asset stripping with no consideration for the other local business it has killed, many survived on match day takings.
