Kate Garraway clashed with a Good Morning Britain guest over the case of Sarah Everard, as police are now under fire for failing to stop one of their own.
Former policeman Wayne Couzens was sentenced to life for the murder of Sarah Everard.
He pleaded guilty to the kidnap, rape and murder of the 33-year-old in July this year.

But now questions are being raised as to why the vetting process for Couzens failed and why the police turned a blind eye to two incidents of indecent exposure by him.
Tory MP Kit Malthouse, the Minister of State for Crime and Policing, appeared on Good Morning Britain to answer questions from hosts Kate and Ben Shephard.
Kate asked: "How many other situations are going unvetted?
"We know that a huge number of allegations have again been put against serving police officers - 750 - of sexual misconduct.
"Very few of them led to charges."
She went to say this was not "confidence-inducing" and added: "Now, that might very well mean that some of the others were unfounded - we don't know the detail of that.
"But it's not confidence-inducing.
"And the practical reality that if someone is nervous - which they will be over the next week at least - calling 999 to call another police officer to take time away from that police officer going to sort out another problem.
"That is the solution to that problem today from the policing minister?"
MP Malthouse replied: "These are instructions issued from the police themselves, guidance those in doubt about the validity of a plain clothes police officer in those circumstances.
"And unfortunately that is the profoundly difficult situation that the Metropolitan Police have found themselves in because of the action of this man.
"Look, there are lots of things that we can and should do and we have been looking at vetting over the last few years to make sure that it's as tight as possible."
However, Kate interrupted to ask whether an officer is suspended from duty or whether they're still out serving as a police officer while a number of allegations against them are being investigated.
Mr Malthouse answered: "Allegations are made every day against police officers - they're in naturally confrontational situation.
"What we have is a system where the public can go to the force and require action to be taken or an investigation and if they're dissatisfied with that they can be referred to an independent body - the Independent Office for Police Complaints - who will look at it independently and investigate.
"Now, in some circumstances, suspension is warranted and that happens in a number of cases.
"In others, not. It depends on the nature of their complaint.
"But what we need to do is make sure that the public have confidence-"
However, Kate interjected once again, and said: "Yes, but that's part of the problem.
"Where you make confidence by having it in practice.
"For instance, if there was - no, no."
Kate and Mr Malthouse carried on with the confrontation, with the MP saying that good, serving police officers rely on the system working correctly also.
