If you're near the scene of a tragedy, don't whip out your selfie stick.
Either help, or get out of the way so the professionals can get through and assist those who've been hurt.
On Wednesday, March 22, after an attack at the UK parliament that left at least four dead, including the assailant and a police officer, a man appeared to be taking a selfie as ambulances arrived.
The attack, which is being considered a terrorist incident by officials, also left at least 20 injured.
Engaging in self-absorption during such a moment is completely insensitive and exceptionally insulting.
"But first let me take a selfie" should never be someone's first instinct if they've just witnessed — or are nearby — a tragic event.
Many on social media are, understandably, furious over this image.
This isn't the first time we've seen people take selfies at inappropriate moments or locations.
It seems to be one of the most unfortunate trends on social media.
A young woman generated similar outrage to the man at the UK Parliament attack when she took a selfie at Auschwitz.
Similarly, this group of people decided to snap a selfie after an explosion in New York City's East Village.
The internet is one of the most incredible advancements in history. It's provided us with an unprecedented amount of information and entertainment.
But, it's also created an avenue for people to engage in extreme levels of narcissistic behavior.
People died in London today, and there's a good chance their loved ones will see the image of this man holding up his selfie stick with no concern for the suffering of others, and they will have to deal with the pain of his utter disrespect.
The immense selfishness of such behavior is emblematic of why we've failed to overcome so many of the biggest problems we face as a species.
Too often, people immediately think of themselves before others, and it's holding us back in immeasurable ways.
