Being a crime scene investigator isn't always easy. It may look interesting, a lot of the times it is, but you may have to work any time of the day, even if you havn't slept in 24 hours. You may be called anytime in the day for example, you might be called to work on Christmas day, or 30 minutes before you want to go to bed. If you want to have this job you have to be ready for any challenges ahead of you. If you feel uncomfortable with something that has to do with this job, then it may not be for you. For example a lot of people do not like going under houses, you may have to if your looking for a cartridge or something. So what I'm saying is that you should know what your going to have to do, before you get the job
