The nearly nude women who trashed a Florida McDonald's was a popular topic on social media last week.
What caused the online frenzy was idiotic employees who leaked the surveillance video clip online (appearantly by filming the monitor with a cell phone), humiliating the women and getting themselves fired.
Here is a video synopsis.
Presumably, employees at the location need access to the system so it might be hard to lock them out of it completely but perhaps restricting access to live video only (without a special user level / password) would minimize such risk.
Secondly, what do you think the legal liability is for McDonald's? Certainly this woman damaged the store but (1) it is not appropriate to respond by humilating her online and (2) the women claims to suffer from mental health issues, making it look even worse for McDonald's.
