Good analysis. Just think of it... Set off a big bomb and kill a bunch of innocent people there, while far away simultaneously attacking and murdering a bunch of helpless kids marooned on a little island. It takes an unbelievably evil mind to dream up something like that. It seems that something more is going on than one guy's simple hatred of muslims.
He didn’t get onto the island until 1-2 hours after the bomb.
In fact, it was the bomb that allowed him access to the island, dressed as a cop. All of the island security was on the “front door.” After that, nothing.
