Nah, they weren't rioting for nothing - they were rioting because a line was crossed.
If they let the PM push things through in that way, the battlelines will just be around a more important issue, and they'll be in a much weaker position
Cops murdering a child isn't "literally nothing", it's a very good reason to riot. Just because it happens so often here that we're desensitized doesn't make it any less abhorrent.
