@Since when was Rioting a civil liberty?
Fail yourself, because you missed the bit that says "I Don't Care About The Consequences Just Make Those Baddies Go Away"
Too many people are willing to say "Fuck Civil Liberties" as soon as any trouble breaks out and they're happy to come up with lists like that which will "solve" the problem.
The fact that what that will leave after may be *worse* doesn't seem to occur to them. (Remember ID cards et al? What if we had them now? Would the Rioters be carrying them? Should the Police stop *everyone* on the streets and check them for ID cards and arrest *anyone* who doesn't have one, even if you've just popped down to the shops, come back to find trouble has kicked off and you forgot to pick up yours??)
