“There is no way she walked out of the store with the sensor tag still attached the first time. The racket made by those things is unbelievable. The only way would have been if it was tucked into a Faraday cage.”
RF reading is not 100% foolproof and depends on many factors. This does happen to people.
Happened to my mother several times where the tag did not beep. She had to go all the way back and have it removed.
Unfortunately you are far more likely to be assumed to be a criminal and violent if black. There is no question about it. The sales ladies were likely afraid she would get violent if they questioned anything. And they likely assumed the machine was foolproof.
You can debate “why” to the moon but there is no denying that statistically blacks commit more violent crime. It is perfectly logical to be more suspicious of black strangers. However, the law does not allow for that and they will be sued if her case is proven on camera
I like to think that it’s more about the way they’re dressed, the way they’re made up, and their general demeanor. I don’t trust sketchy looking whites any more than sketchy looking blacks.
