TV Cop Shows

Ever notice, when you're watching a cop show, the detectives go to interview somebody who may have some important information, and the person they're interviewing goes on about their normal business while giving offhand comments to the detectives?  It's like the cops are no more important than some delivery boy off the street.  I dunno about you, but whenever I get interviewed by police detectives, particularly in a murder investigation, they get my full, undivided, completely focused attention.

Just a thought after watching another episode of Law & Order.
