Best friend of murdered teen Stephen Lawrence, Duwayne Brookes, said “Khan as Mayor is weak and ineffective”.
The Mayor said: "Londoners have responsibility too.
"We (meaning you) have got to be the eyes and ears of the police - if you see something that you think is a criminal event, ring 999.
"We've got to help the police do their job in these difficult circumstances, keeping us safe."
Quite a hard call as you just don’t see officers in central London that often. Victims of crimes complain that calling 999 doesn’t mean anyone will turn up!
Khan went on to repeat the claims that the police don't have enough money. He said it would be "naive" to say that cuts had not had an effect.
This from the Mayor who sold off police buildings, closed police stations and cut numbers to finance the £bn cycle super highways.
Mr Khan said: "Our police - and it's worth just saying this again, are cancelling their rest days, they are working overtime.
Truth is there’s just not enough manpower anymore to keep citizens safe. The Mayor has again put profit before public safety.
