But in this case...
There was no sign of police or any kind of law and order.
Better to be well armed with something considerably more effective than a machete.
Yesterday, my husband, walking back to his office after lunch, was almost run over by a guy. When DH yelled at him to watch where he was going, the guy backed up and nearly ran over his foot. DH pounded on the car. Driver yells, “Now I am going to get you good!” and gets out of the car. DH held up his cell phone, asked the guy to smile for the camera and not to forget the ones on poles. The driver looked around, by-standers were smiling and he got back into the car and left the scene.
What no one else knew was that my husband always carries a knife. He had his hand on it inside his pocket and he knows how to use it quickly and to effect.
But, for this incident, in a peaceful American city, the cell phone camera worked well.
