You’ve identified a part of what I think - that whoever abducted Gerard didn’t intend to kill him at the time of the abduction. I think circumstances changed for whatever reason. Could have been that Gerard was difficult, could have been that he was nosy and found out something he shouldn’t have (such as someone’s identity specifically), could have been that publicity made them nervous.People don't expect to be seeing a child being abducted though & many people often turn a blind somewhat sympathetic eye to someone having to deal with a child being "difficult" in public. Who's going to interject if the assumption is its that persons child & particularly if that child appears to go with them happily after being fed a story.
They only appear more brazen than you'd expect because they don't have to be any other way & they still fly under the usual radars. We notice someone scoping a house or a car because its not usual. A parent snatching up their child & briskly walking away or even dragging them by one arm with their feet barely skimming the ground, perhaps even screaming as well, isnt something you tend to stop in your tracks to watch. You look away if anything, not expecting for a minute that your witnessing the child being abducted.
But, for someone with the intention of killing a child and leaving him where he was found easily whilst not having any fear that they may be caught, I dont buy it. They could have just got in their car & removed all reason for any witness to recall anything about the incident. Then picked him moments later after they moved on.
I think the people who abducted him either had no part in his murder or what was to happen to him after they did "their bit" in abducting him & delivering him to someone else, or they had no fear of being identified. The only other alternative is they were just supremely confident the cops couldn't solve a case if they tried & were prepared to risk spending their lives in jail if they got unlucky & I don't buy that either.
It may also be that the woman seeing them pushed them past the point of no return. At that point they had her having seen them AND Gerard. Plus if they had let Gerard go at that point, I imagine they assumed he would have run, and the woman in the car could have stopped then or paid even closer attention.
And I agree child snatchings are brazen for the reasons you indicated. My comment was more simply the fact that they are brazen, and that I see no reason to be shocked about the brazenness of this one if what the woman saw was correct. There are times when kids are grabbed in shopping centre car parks in full view of cameras and onlookers and it’s hard to solve. I’m not sure that a woman in a car peering at them would have been of particular concern.
