If Cameron supports, they will oppose

Cameron, Myleene and tabloid tales
Essentially, then, the word of a celebrity TV presenter is regarded as being more credible than that of the police.
What? Coppers not telling the truth, the whole truth and nothing but the truth? I can't wait to see Anton Vowl repeat that line next time a demonstrator (maybe even a Labour supporting celebrity) complains of being roughed up by police and the cops issue a vehement denial. Or maybe when an innocent man gets shot in the head seven times by armed officers.

Andrew Bartlett, in the comments, equates waving a knife in your own home at some guys outside, who are clearly up to no good, with carrying a concealed blade through the streets of south London.
Myleene Klass felt threatened. Decides that reassurance lies in the shape of a knife. Public support. A young person - the most likely victim of violent crime - feels threatened. Decides that reassurance lies in the shape of a knife. Public damnation - with calls for jail sentences for carrying (not using) a knife.
I won't even bother to comment on that. It's just plain bonkers.
