These riots look a bit more serious than the previous Irish chimpout. I am still very skeptical they will lead to anything relevant. I've seen random people attacked, some black dude getting punched, not generally a good look, but hey, I guess beggars can't be choosers.
The real target here should not be the migrants, but the government, obviously, as it's the power structures that allow all these people in.
To remove them, you need government power. No Irish or Brit would participate in pogroms or anything like that, which has a chance of making people flee because of the savagery.
So government has to be replaced, police must be made to serve the new government, laws need to be written, and migrants expelled orderly.
