I think its likely that these people would go home dismayed, but keep their radicalization and try more shit elsewhere. However these people very openly displayed their faces and showed a clear lack of organization, I think its also likely that a lot of them will be arrested in a crackdown. I suppose in the end the only way to know what happens long term is to just wait and see, personally I just hope that something happens to stop them from going on and doing something truly heinous like a mass shooting or lynch mob.
