What if you purchase new GE appliances for your home and when you purchase them the company says that they have a policy to make sure the home is safe and free of firearms so they will need to search your home before you take delivery of the appliances. This could apply to almost any business transaction. Again does a business have the right to search you or your property as a condition to doing business with them? I think the answer is clearly no.
Can anyone tell me when the American people ratified the NFL as a governing entity?
If the NFL has not been ratified as a legal government then they can't search you, period. This applies to all businesses and private entities.
