You have produced nothing of value. It is possible to hide bodies and later move them. It has happened many times. You can get to the cliffs. He is not walking through the streets to get there. He is on the deserted beach. You're not going to find anything taking a stroll along the beach. Not many torches and Gary Lig said it would be impossible to search that area properly in those conditions. We know certain people went out hours later and were all alone apparently.
Gary Lig at the beach

I have no intention of discussing Gary Lig's view of the case further, given he has clearly demonstrated his total ignorance of critical facts.
How on Earth can you say you can get to the beach without walking through the streets? What? You cannot be serious.
Does Smithman now magically have a car? Does he levitate to the beach?
Smithman had until perhaps 10:20PM or so to get to the beach before numerous people are crystal clear that the beach was a place they searched.
There were NUMEROUS places open on the beach front until later than that. A Concha, Paraíso, Habana, Lazuli, Carlos Bar, O Poço, the nightclub.
And if you are factoring in the later time that the McCanns reputedly searched, try checking the Habana webcam. The set-up crew normally are active before dawn. The beach cleaners are out first thing. People let their dogs roam free on the beach while they socialise with other dog walkers. It happens to be an extremely attractive and tranquil place to be at dawn.
I know because I've done it. How about you? How about Gary Lig? Just another guy who does not know how Luz runs, on top of seemingly being ignorant of the facts of the case.
Is it possible we could stick a bit closer to the topic rather than throwing in unrelated quotes from a Dispatched programme that did not have access to the facts? I feel sure the mods would appreciate this.
