Depends on the business.
You know perfectly well the 4th Amendment makes no exeption for that.
Depends on the business.
Maybe so. But let's stick to the main point of contention which is: The fourth amendment refuses government access to a person's home, property or business without a properly signed warrant. Yet the government forces business owners to give access to total strangers via discrimination laws. In effect the government, taxpayers' employees, can't be trusted, yet the same government that can't be trusted proclaims that business owner must trust total strangers.
