A National Criminal Records Check can be run for a variety of purposes: Pre-employment and Tenant Screening are among the most common reasons that criminal background checks are run for business or commercial uses but private individuals may run a criminal background report on people that they might be interested in dating or on a new neighbor across the street just in case he/she is a sexual predator. Most people run criminal background checks simply for the peace of mind that only the power of knowledge can bring. We all want to feel safer and more secure!!!
