4 in 5 days. It's out of control. I don't know what the answer is but I do think that anyone caught carrying a blade should be handed a minimum 5 year sentence. Flood the streets with police. Build more prisons. Deport any foreigners involved in gang violence back to where they came from as I don't want to pay for their prison upkeep thank you very much. That's a start. Better than anything Mr Khan can come up with.
