This is why you should ALWAYS keep your swimming pool safety enclosed. A home security cam caught a one-year-old walking on the wrong side of a pool fence while his dad sat nearby having a drink on the patio. Then the kid falls into the water.
Luckily the dad saw it so he took off running and dove over the four-foot fence to save the boy. There were other people in the pool so they may have been the ones who left the fence open. The father and his son are both okay.
