No, modern "detecting" is about workflow. The first real duty-related thing would be booting up the computer, signing onto the network and finding out what cases the boss has assigned. So, imagine if you will, a case where a prominent citizen - perhaps the president of something - has stated on separate public occasions that he was born in Kenya...Hawaii. "Wait, it will come to me," he exclaims. The detective turns off the computer, takes an Advil and heads for the gym.
Forget context, how this isn't really an issue and we all know that Barack Obama was born in Hawaii. Forget that our hypothetical detective (actually, in Arizona, a very real task force exists) in our hypothetical police department wouldn't get this case in any normal way. Any trained investigator would begin with a simple question.
