don't believe the cause of the marco polo fire was due to any mechanical cause, but to human error, intentional or otherwise.  hence, this could lead to huge lawsuits against the owner of the unit by the other residents who suffered damage of property and lives.  it will eventually have to be disclosed since there will be lawsuits brought against the owner anyway.  this is why these council members are now saying that maybe installing sprinkler systems in all condos may not be necessary, since it has been several years and this was the only large damage fire.
