Not really. And most times there is nothing there anyways and its all insured.
Thats the mind of a racists.
They have preprogrammed their minds to terrorize black and brown people when the majority and dominate are doing and causing most of the crimes because they are the populous in the area.
The behavior and use of alarm is way to say they know you look different and they see race first and their false assumptions first and you should not trust them because they are illegally and racially profiling against you. Especially if their behavior is not discriminative and not based on race.
They, white people, think poor whites wont rob them, but imperfect society disadvantages everyone. So post slavery and exposure to discrimination shows that white assumes there is no justice and economic freedom providence to others and assumes wrongly that anyone is going to seek retribution with any strangers that looks like them.
It is embarrassing that whites and c00ns do that especially when it is racially motivated and they know there is nothing in the car, the glass is not plexi and its insured. There is nothing to lose.
