In my county, here in Texas, there is a high turnover rate in the DA's office. It is a common first job for many new lawyers. They then move on to other jobs. This means that when a prosecutor leaves, someone else must take over their caseload. That person will first have to figure out the case, and the other prosecutor's plan. Hopefully they left good notes! Even so, your strategy on how you would have handled it might be different, but, the case might be too far along for you to be able to make changes to the strategy.
Also, sometimes things get lost, misplaced, or otherwise overlooked along the way. I watched one case where the defense had made the prosecutor's office aware of bodycam video. A new prosecutor came in. The video info got buried. The prosecutor therefore allowed officers to testify that there was no video, and then the defense introduced the video, which made the prosecution look bad!
A good thing about turnover though, is, should you decide to make it a career, you should be able to move up. You will also have the opportunity to mentor the other new prosecutors as they come along!
Another good thing is you learn the ropes of the prosecutor's office, so, if you want to go into criminal defense, you will already have an idea of how your adversary thinks!
A bad aspect, not to be taken lightly: Even though you might think you are doing good by getting bad people off the streets, their friends and family won't agree with that assessment. If you are responsible for locking up a husband, a son, a father, etc, there can be threats made on your life. That is probably the worst thing I can think of!
I really think the good outweighs the bad, especially if you want to later go into criminal defense. Either way, I look at all jobs as stepping stones to the next job. Things aren't as permanent as they once were. So, try it!
