Nope, that does not meet the standard. However, what often happens is that “reasonable suspicion” is used to bully an owner into allowing the police in. This is often combined with vague threats of retaliation or retribution should the cops be forced to go get a warrant. Once the owner caves in, and gives permission, they have obtained what they wanted.
don-o raises a good point, but I don’t think it attaches here. A condition of having an alcohol license includes permission for beverage enforcement to act on your property. If you don’t let beverage enforcement in, you get shut down, pronto, and lose the license.
