The Westminster attack that left four people dead and forty injured is not the first time that security personal and the civilians of London have become victims of terrorism.
On the morning of the July 7th, 2005 four Islamist extremists separately detonated three bombs in quick succession on the London Underground system during rush hour.
A fourth later exploded on a double-decker bus, 56 people lost their lives 700 suffered injuries.

The latest carnage included no bombs and no subterfuge, just a car and a knife.
These everyday articles have become the weapons of choice for Islamic terrorists and have been trumpeted by extremist websites and publications.
Since 2010 al-Qaeda has been encouraging the use of large 4×4 vehicles to move undetected through cities to inflict the maximum amount of carnage and spread fear.
On May 22, 2013, off-duty British soldier, Lee Rigby, was run over by a car then hacked to death by two men using a knife a meat clever.
They dragged his body into the road and waited for the police to arrive.
Such brutal methods have also been encouraged by ISIL.
The now dead spokesperson for the group, Abou Mohamed Al-Adnani, urged fanatical followers to plan as little as possible and use whatever came to hand to kill and maim.
In Quebec, Canada, in 2014 a 25-year-old convert to Islam rammed his car into two Canadian soldiers in a shopping centre.

The methods used by terrorists are now extremely cheap and simple.
The lack of logistics, structure and planning make it difficult for intelligence services to thwart attacks in the pre-planning period or protect the public when they do occur.
Most agree that recognising radicalisation and monitoring are the most effective defences against attack and if they do occur governments have procedures in place to minimise the impact.
