For those who witnessed or lost loved ones during other terror attacks Friday's killings on London Bridge are another painful reminder of their broken lives.
Brendan Cox, the husband of murdered MP Jo Cox, is one of more than 70 people affected by terror who has signed a letter demanding change and more support for those left behind.
In Brendan Cox's own words, the worst thing that could have happened to him has happened. In 2016 his wife was murdered in her constituency.
Jo Cox was shot by a far right extremist. After her death Brendan set up the group Survivors Against Terror.
In a letter signed by more than 70 victims of terror attacks they have called for the creation of a 'Survivor's Charter' with better support for victims and a security plan in all public spaces.
The grieving parents of London Bridge victim from two years go, Sara Zelenak, expressed their frustration of enduring a long inquest and authorities not learning from their daughter's death.
Survivors of terror have been through the worst and all victims deserve all the support they can get.
