Regardless of whether or not background checks are effective, if you don't require them you are increasing your chances of being sued when (not if) something bad happens. At the very least, speak to an experienced lawyer about it.

Women can be sex offenders as well as men. Something that is over looked but background checks help to reveal. You can have a mother with videos of her children and photos and not know she is a sex offender with prior convictions.

It only takes one to get a civil suit.
