There was a time when people basically lived all their live's in the same place they were born and mostly everyone knew who was to be trusted and who was not.
Those days however, are long gone and their part of our history.
These days, anyone with a credit card can walk into a Uhaul facility and rent a truck and move anywhere they chose to with extreme ease.
That is why businesses are doing national criminal background check on almost every person that they hire and be certain that this person is not a wanted felon on another state.
Every day, millions of americans that are the head of the human resources department at their place of employment or their own business go online to one of the many web services that are linked to FBI criminal background databases and run background checks on any potential employees to make sure they are fit for employment.
People that own real estate properties and that lease them to others also use these services to check personal information on renting candidates to avoid themselves the hassle and headache that a bad tenant can bring them.
Also, those who frequent online dating services to find and meet friends and possible love partners are turning to these online services and check the person's information to be certain that this new possible love is not a sex offender or a predator wanted by law enforcement authorities.
Lastly, people can run a national criminal background check on themselves to make sure that there are no incorrect entries and have them correct it in case there are.
