Yuri Melich, Chris Serino, and Esteban Flores may not be names you recognize, but they all have had their 15 minutes of fame in front of millions of TV viewers. In contrast, Casey Anthony, George Zimmerman, and Jodi Arias are names you probably recognize immediately.

The first three names belong to police officers, detectives, and leading investigators in the cases against the three more famous names, who were all defendants in very high-profile murder trials.

You should be paying attention to such trials not because they are high-profile, media-centric circuses, but because they offer all law enforcement officers a glimpse into what it will be like when our cases make it to the big time.

How do you know when your case is going to put you on the national stage? When it does, will you be prepared to defend what you did or didn't do in front of a national audience?

Thousands of officers and detectives investigate violent crimes every day. First responders cordon off crime scenes, interview witnesses, and collect and preserve evidence. Detectives follow leads, interview people, and put their cases together for prosecution. Among these thousands of cases every year, only a very few become high-profile media magnets like the trials of Casey Anthony, Jodi Arias, and George Zimmerman.

The detectives listed in the first line of this column were just working a case assigned to them the way they do every other case that gets tossed on their desks. The difference is that these three cases garnered public and international media attention. I can't say exactly why, but these cases stood out. There are plenty like them, but not all get thrust into the national spotlight.

When your case generates a frenzy, how will you do on the witness stand? How will you weather the intense scrutiny of your every move, every statement, and written reports? Will your work be unsullied or fair game for the defense?

You should study these famous cases. You should pay attention to the detectives on the stand. Pay attention to what they did right and what they did wrong. You should also be paying attention to what questions are being asked and why.

In spite of how "modern" policing has become, criminal cases always fall back to the very basic and well-established police procedures. Time after time, we see the basics of police work targeted by defense attorneys. Why? Because its important to get the basics right. If you don't, the consequences can be high.

So we need to pay attention to the basic, low-tech ways that we do our jobs. Putting up crime scene tape is low-tech and may seem mundane, but it can be the difference between getting that critical piece of evidence or having someone accidentally kick it down a nearby drain. Separating witnesses is a basic police procedure that we are all taught at the police academy. But if you don't do it, you risk contaminating the witnesses and not getting the right accounting of what they saw or heard. If you put "wet" evidence in the wrong kind of bag, you can wipe out its evidentiary value. All of these are very low-tech procedures, but failure to execute them properly can be the difference between conviction and acquittal.

Attorneys in very high-profile cases brought these and other very basic police investigative procedures into question over the past few years. In the three cases mentioned previously, police investigators found themselves on the stand answering questions about what they did and how they did it.

So what can we learn from high profile trials? First and most importantly, you have to do the best job you can with the best equipment you have, and you need to use well-established procedures for handling evidence, interviewing witnesses, and documenting your case.

Your best insurance against becoming infamous for sloppy police work is to work each case like it's the next "trial of the century." Don't cut corners just to get the case filed and off your desk. It can come back on you in a big way. And envision yourself on the witness stand, defending the work you did. You want to be able to walk away from the defense attorney's grilling proud about what you did and proud of case you helped put together.
