The London Bridge attack left dozens of citizens injured and 7 dead. The attackers stabbed random people who became sitting ducks because the police ran away. The helpless people resorted to throwing chairs at attackers. If someone in the crowd had been armed, those lives could have been saved.

Guardian reporter Lisa O’Carroll is at Borough Market, where she says multiple stabbings have been reported:

Witnesses said they saw two men stabbing people outside the well-known Roast restaurant in Borough market. A chef from the nearby Fish restaurant said: “I saw two guys with big knives downstairs outside Roast. They were stabbing people. The police were running away, they were community police. They were normal officers, they were running away.

“The guy with the knife was killing two people. We were shouting ‘stop, stop’ and people threw chairs at them. Police came and shot straight away.”

Another staff member from Fish said: “I saw two people in Breadhead bakery, they had blood on them, they were civilians. I never expected to see this happen here.”
