Thank you for your follow up.
I cannot comment on your specific case, but generally, unfortunately, the store in fact can pursue criminal charges with the police and state prosecutor after the alleged crime took place and it would be up to the prosecutor to decide based on evidence, such as video tape, etc...whether probable cause exists to charge a person with a crime of shoplifting.
Also, Walmart is a private company and can ban any person from using / entering their store for any reason (except illegal discrimination) or no reason at all, so yes, Walmart can ban anyone from entering their stores.
Also, once a copy of the ID is made, it becomes the property of the store, given the fact that the shopper did not object to the request for ID and handed ID over voluntarily upon request, so the copy of the ID does not have to be returned by Walmart.
It would generally be a good idea not to communicate with anyone about this potentially criminal matter and to consult and retain an experienced local criminal defense attorney and to let this local attorney handle this legal issue for you.
You can find an experienced and skilled local criminal law attorney by using this established and reputable attorney information / referral websites:
When, choosing a local attorney to represent you, it would be a good idea to choose someone who has a practice exclusively dedicated to criminal law, has at least 10 years of experience and handled similar matters and also regularly practices before the court located in the jurisdiction where your matter will be heard.
I wish you the best of luck!
