Perhaps liberals could help Officer Crawley ...?

For some reason, Officer Crawley couldn't determine whether Professor Gates actually lived in the house where a burglary was reported from the Harvard employee identification card that Professor Gates gave him. As experts in law enforcement, how would you liberals have used a Harvard employee identification card to determine that Gates lived there? Officer Crawley was stumped by the lack of an address on the identification. He called the Harvard University police for help in confirming Gates' address. Clearly, you liberals think that was unnecessary. So, how would you liberals have determined that Professor Gates lived in that house using that identification card without any address on it? Is the liberal approach to law enforcement merely to take a person's word for it? If so, wouldn't that make burglary really super easy to do?
