ISIS claimed responsibility for the London Bridge terrorist attacks on Saturday where seven were killed and 48 were wounded.

It was the second deadly attack to occur in the UK in under two weeks.

But there is one fact about the tragedy that will make your blood run cold.

At least one of the three jihadists had been previously notified to British authorities.

The Telegraph reports one was referred to the police twice for his extremist views:

“One of the three jihadists who murdered revellers in central London on Saturday had been reported to the anti-terror police on at least two occasions, it has been claimed.

A former friend of the terrorist, who was shot dead by police along with two accomplices, claimed he had been radicalised while watching YouTube videos and said he contacted the authorities ­after becoming concerned over his friend’s extremist views.

A neighbour also claimed she had contacted police in Barking, east London, after the suspect tried to convert her children to Islam and radicalise them. The man is not being named at the request of the police.

The former friend claimed he contacted police after comments the man made about other previous attacks. But he said the authorities had failed to act and take action despite evidence of increasingly extremist views.”

Why did the authorities decline to act?

The Manchester bomber – who carried out a deadly suicide attack at a concert – was also known to the police.

CBS News reports:

“Police on Tuesday identified the man who blew himself up the previous night at an Ariana Grande concert in Manchester, England, as 22-year-old Salman Abedi. CBS News confirmed Abedi was known to British authorities prior to the attack.”

Donald Trump tweeted that it was time to stop being politically correct and for the Supreme Court to uphold his executive order restricting travel from six countries tied to terrorism as well as suspending the refugee program.

Why did the authorities refuse to act when both terrorists were known to the police?

Was it because of political correctness?

Were the police afraid to move against two members of London’s Muslim community?

These are serious questions now being asked in the wake of the attacks.
