What did they expect the Ramseys to do with Burke? Send him to school with body guards? In an armored car? The Ramseys clearly wanted to get Burke back into HIS routine and in familiar surroundings with HIS peers. This whole time frame was incredibly traumatic for the entire family. As Patsy said, Burke was her only remaining child. Their world had been completely rocked. Their sense of security had been completely torn down. Someone came into THEIR home, while THEY slept, and murdered THEIR child (NOT Kane's child, not my child, and not your child). I think this attempt at some degree of security was a compromise between getting Burke back into his familiar surroundings and comfortable with his world and keeping him under tight surveillance. An armored car and/or body guards would have heightened his fears (very extreme). SOME attempts were made to keep him under the watchful eye of several adults, but not in such a way as to be invasive, add to his uncertainty, and hinder his re-entry into his comfort zone.
