ON Wednesday morning, a police officer most probably kissed his family goodbye and went off to work.

Hours later, he died on the street outside the Houses of Parliament, watched by the eyes of the world.

Keith Palmer probably didn't consider himself a hero.

Nor, I'm sure, would the civilians, politicians and workers from a nearby hospital, who rushed to help those in need, consider themselves heroes.

But in moments of evil and terror, it is these people who should be our focus.

The ones who, with little regard for their own safety, run towards danger to help others.

Keith Palmer died, yes. But his actions- to stand in the way of a man with a knife- may well have saved the lives of many others.

That is true heroism.

What happened on Wednesday is beyond comprehension.

And though the attack was an act of pure evil and hatred, in the moments that followed there were demonstrations of love and kindness.

As Fred Rogers once famously said: "When I was a little boy and I would see scary things on the news, my mother would say to me 'look for the helpers, you will always find people who are helping.'"

The photos of MP Tobias Ellwood, covered in blood, desperately trying to save the life of Keith Palmer- shocking as they are- are symbolic reminders of the unbreakable human spirit.

They show the capacity of man to put himself in a dangerous position to help his fellow man.

People like Keith Palmer and Tobias Ellwood sum up what it means to be British.

And we are all British- regardless of whether we were born here or not. We are one nation.

A nation that should always be welcoming and and strong and united.

Our differences should not divide us. They are what makes this country a diverse and wonderful place to live. 

Terrorists like the one who attacked Westminster are not the face of a whole group of people. 

They do not represent us- any of us. 

Those who represent us are people like Keith Palmer and Tobias Ellwood and all of the others who acted to save lives on Wednesday.

We must not let hatred divide us.

We must come together in the face of terror- regardless of our race, religion or background.

We must continue about our daily lives, defiant against those who view our freedoms as crimes.

It will be hard to forget the horrific images we've seen. 

But please, don't let the photos of the terrorist be the ones you remember. 

May the images that stay with you be those of the heroes that put their lives on the line defending those freedoms. 

And may you stand with your fellow man, against terror, as they did.
