This is not about "dangerous and criminal p0rn", it is about any #*$!. The filters will block #*$!, discussions about #*$!, stuff that it looks like it may be #*$! (see my example above).
The UK already has a filtering system for illegal material (which has already become much wider than it is supposed to be - e.g. blocking online versions of images legally on sale in paper form). This is an additional filter which will block all #*$! (and a lot of false positives).
