As the 7/7 families hugged each other inside, and outside, the cathedral, nodding to each other in tearful support, I saw people who had all experienced an ordinary day turning into the worst possible nightmare of any parent, spouse or sibling.
Perhaps the most pleasing aspect to this book, therefore, is that the contributors have used their own freedom of expression to defend the free speech rights of others. It is a positive and creative response to a moment of destruction, and should give us cause for hope.
A decade on from 7/7 its a day that has and is shaping things to come for my generation as we all continue to feel it's consequences - but difficulties often prove to be the most testing of times, pushing you to make choices and the 7th of July 2005 was a difficult day for London.
Like many Londoners, 7 July 2005 began for me as a normal working day. I drove from my flat in Queens Park to Ealing where I was working as an estate agent. Morning briefing done, our team of sales negotiators 'hit the phones' to drum up business and book appointments. Then people's mobiles started beeping. Other offices started calling in. Something was going on in central London.
Islamic State, Cameron says, is neither Islamic nor a State. He's right - on the other hand, nor was the Irish Republican Army ever an army. So what? A name is no more than what someone chooses to be called. Does he really think that a single one of IS's recruits was attracted to its ranks because they were misled by its name?
What to do when our intelligence agency, MI5, state the terror threat level is severe? Iain Dale spoke to a member of the public on his drive show on LBC last week, who articulated why he believed we are looking at a generational fight against this particular breed of terrorist: IS. David Cameron went further and said they pose an 'existential danger.' The truth is probably somewhere in the middle.
Gunmen and bombers left a swathe of death and injury in three terror attacks in Tunisia, France and Kuwait this weekend. They took the lives of at least 60 people and injured more than 200. As the news poured in, the funerals were taking place of those slain in another crime motivated by hatred and designed to sow terror - the nine people shot in the Emmanuel AME Church in Charleston, South Carolina.
So, when my children are old enough to hear the news and understand, what will I say? Will I tell them that some people kill to express their differences? Will I reassure them that these things happen far, far away from us? On battlegrounds?
Cameron blames the Islamic value system for extremism in the world today - I find such a statement totally ignorant and unenlightened.
Mr Roof is clearly a terrorist, he killed nine people in a racially motivated crime, he sat in the church with them and then let off gunshots, mass murdering them all. This is not just a hate crime, as many organisations like to make out.
An Iraq/Syria-based adherent of the self-proclaimed "Islamic State In Iraq and Al-Sham" terrorist group has been caught out online complaining about 'missing Starbucks' coffee. While seemingly trivial, the complaint actually offers a remarkable and rare insight into the entitled, privileged, westernised and deeply selfish mindset of ISIS's followers.
In today's 24/7 social media and headline-driven world, the average Muslim wakes up each day either surrounded by a depressing narrative on the Islami...
According to one of the most senior Muslim police officers, we should be observing children as young as five and looking to monitor and detect the earliest signs of anti-western sentiment. What does this mean in practice?
What the liberal-left is practicing here is a worse form of Islamophobia - the fear of offending Muslim extremists. And White writers assuming that all Muslims get offended by Hebdo's cartoons - as if there are no secular, sober and sane individuals and political movements in the so-called Muslim world - is also a form of racism.
You are deceived in thinking that you are fighting for a 'cause'. I do not know what God you believe in, or what odious rhetoric you espouse, or what your ill-advised political beliefs are that give you the permission to do what you do everyday
After the rejection by the British Parliament of intervention against Assad, he has been given free rein to destroy Syria and its people, creating devastation, chaos and a power vacuum. Into that gap stepped Islamic State, Iran and the Shia militias which have committed brutal and widespread crimes of their own.
