Your first reaction to this business is that - why would you ever need a background screening check? When would you have a reason to do a background check on someone??
The truth is that everyone has a reason. Think about the news and the incidents where violence and crimes reared it's head in the unlikeliest of scenarios. Boy scout leaders molesting young boys, co-workers losing their sanity and shooting up the offices where they worked.
What about personal relationships? If you are out in the dating world, you know that meeting and dating someone is taking a gamble on that person. You're gambling they are telling you the truth - all of the truth. Is your daughter or son dating someone new? Wouldn't it give you a peace of mind to know that they aren't hiding a sordid past?
There are many scenarios where a background screening check would be helpful.
