So busy filming we forget to run away WARNING: Some may find this distressing. Terrifying phone footage of the explosion near Waco, Texas is filmed by a father, leaving his daughter unable to hear. CAN anyone remember what people did before our compulsion to film everything? We've barely had time to lift our heads from Monday's Boston bombing and tragedy strikes again. This time in WACO, Texas where an explosion in a fertilisation plant has left far too many people critically injured and up to 70 believed dead. Some of the most shocking footage of the power of the blast comes from an un-named man, who was sitting in the car with his young daughter, filming the billowing smoke from what looks to be a field from afar. In seconds there is a blast of explosion, black smoke fills the screen and all you can hear is the haunting and terrified pleas of his young daughter whose exposure to the sound has appeared to have left her without hearing. I can't hear dad, I can't hear. Get away from here please, get away. Smartphones have ensured footage like this of every significant and terrible event; and you'd like to think that it could in some way benefit the anticipated investigations. But sometimes you have to wager whether this compulsion to be the first to capture the tragic moment might actually be more trouble than it's worth; risking the safety of people who would otherwise never have been impacted, had they just kept out of the way of danger.
