Real World is not TV
One of the actors in a CSI series commented when asked about this subject and replied that on TV they have to solve a crime in 43 minutes.
The same applies to courtroom dramas. In real life a main witness may spend several days being questioned and cross examined.
In Medical shows it may take a doctor weeks to compete a full series of tests. A simple analysis of a bacteria could take several days.
With cyber crime the all these magical tools used on TV simply don't exist or if they did very few policing departments could afford them. Face recognition software for example is not where as sophisticated as we a re lead to believe. For every on person on earth there are thousands of others who look similar so getting a "hit" as they do on TV is just not possible.
Unfortunately people expect the same instant results as they see on TV.
