jmt47,

Applicant screening DID keep the son of an HPD detective from the force.  You may remember him.  While employed as a rent-a-cop at a now defunct Woolworths, he murdered his girlfriend and disposed of her dismembered corpse in the nearest dumpster.  Not to scare you, but it's entirely possible he made parole several years ago and is living right there in your own neighborhood.

Cheers!
