Surely some still remembered that Bruce had previously gone to Metropolis to investigate a serial murder case, while Clark had taken his place and begun maintaining order in Gotham.
Clark was at a loss when faced with the tangled and complex relationships among the gangs, but he was the natural nemesis of supervillains.
Gangs usually fought over interests. It was hard to say who was right or wrong. They seized territory to make money, and made money to live better. If Clark wanted to sever that chain of interests, he would have had to rebuild all of Gotham from scratch. He did not have that ability.
