One of the most traumatic places can be a crime scene. Yes there are different types of crime scenes, but surely, without a doubt for at least someone involved that scene has traumatized some there involved. That can be something that counseling can help heal and overcome. People heal with scars, you see. They do not heal perfectly like it never happened.
Now, if someone can make a scene like it never happened, well, that is something to applaud. There are such places for crime scene cleanup services (see more at https://bit.ly/2K2NdZI) that really do make it like it never happened, and that in itself is fantastic. That can definitely be a catalyst back towards a sense of normal. To take away the appearance of how a crime scene looked; now that is a job for the professionals. You do not want to take any chances with what is on site of that scene. Not always can it truly ever be back to normal or back to they way it used to be, but clean surely has some weight to it. More than clean is part of the goal, that’s for sure.
