If Labour (or left figures) push any narrative of this being ridiculous then the Tories get what they want.
If Labour don't say anything then this will be pushed up the agenda as something the Tories see Labour not wanting to touch.
Therefore Labour need to go in quick and hard with absolute support for any measures that reduce criminality and illegal immigration (it doesn't matter what the existing law is, that's not the point). Pushing it back at the Tories as them not doing enough is even better as it nips it in the bud and removes it as a weapon come election time.
