I think sometimes we have a false idea of how innocent people act, just as we have a false idea of how drowning children act. Drowning children drown silently, seldom calling for help, as they quietly gasp and sink below the surface surrounded by people who, if they knew, could help.
Innocent people often just sit there looking stunned, and silent. Think the olympic bomber debaucle and that poor guy who died in jail on suspicion of kidnapping Elizabeth Smart. They both adopted a typical innocent person's demeanor - deer in the headlights. Guilty people often bluster, lead searches, demand that LE find the "real" killer, etc. Innocent people often just sit there looking stunned, unable to muster the energy to defend themselves.
I also have to point out, not knowing what "honey wax marijuana" is, but having experimented with reg'lar old marijuana, I could think an hour was about 10 minutes, and forget completely a meandering route I took in a car. Not that it's good to do that with a baby, obviously, just saying that this honey wax stuff seems like it could be responsible for his inability to remember where he was, and a clear accounting for time.
Can I ask what you believe happened if MG wasn't responsible?
