Are background checks enough?

Well, are they? I think not in every case. I firmly believe that even as long as 20 years ago, more than a routine or even a deep background check should be made on:

Security personnel - all levels, serving any age
Actively teaching Faculty or non-teaching faculty - teaching/advising students age17 and younger, teaching/advising students age 65 and older
Medical personnel - treating 15 years and younger, 70 years and older with additional pediatric or geriatric training as appropriate

The checks I am referring to are two types:

One type is known and used in the Television Game Show / Reality Show divisions called Level 4 (with the addition of whether or not a previous record set has been expunged - if sworn officers)
The other type would be a Wonderlic test.

Well, there you have it, all the votes are in.
