Keith-Some thoughts on your question.
My home in the states is Clarksville TN-their are 2 wal marts in the town-one on the Ft campbell side and the other is near route 24 and the newer part of the city where the houses and area is expensive to live in.
Needless to say the problems occur at the Ft campbell side of town (not because of the 101st airborn soldiers but because of the demographics of the society-the Ft Campbell side gets the Red necks (and i like red necks

)crazies, homeless, perverts, many shop lifters, gangs, etc etc
this causes confusion and problems when the store gets crowded-plus the fact that the security sucks-all of which makes for a long day for the store detective-sometimes only one on duty for a large store
Then you have payday for the field workers, factory workers, people getting food stamps,
the poor , the indigent , the professional shop lifters and lastly the ones who are just looking for trouble.
Thats why people get hurt.
When I am home with Mama and the grandkids I always am observing what is around us
when we shop there. We live near by.
