There is a big difference between background information and circumstantial evidence.
Many a strong criminal case has been built on circumstantial evidence alone. It is undoubtedly valid evidence.
None of your information about cape town tourism is evidence. It is just background information. If it was evidence then you would have been called as a witness in Mngeni and Dewani trials.
I love the way you narrowed it to just mu circumstantial evidence about Cape Town Tourism

On this thread I have posted detailed information about what MILLIONS of other tourists have done and posted links to credible newspaper stories which clearly illustrate going to MZOLI's is a very minority tourist thing to do and millions of tourists have not done it. I have even posted irrefutable evidence that MZOLI's shut an hour before the Dewani's left their hotel, so they could not have been planning to visit it.
I have also poste detailed information about booking a helicopter trip. I have shown that there is a Tourist Information desk at the airport and at the V&A by the hotel which both book the helicopter trips, even if someone accustomed to 5 star hotels where you just get the Concierge to do everything for you forgot to ask them. I have posted a map showing where the hotel is and where the helicopters are to illustrate it is a short pleasant walk between the two and it nuts to suggest you'd take longer driving it or would give a taxi driver the cash to drive round and organise it. I have also pointed out that you can just pick up the phone in the room, speak to the helicopter pilot yourself and pay over the phone with your UK credit card, just as you would here.
I have posted a map with all the banks and ATMs in the V&A so you can see he was only a minute's walk from the nearest and had no need to vanish for 45 minutes with the Taxi Driver
allegedly to change money at an illegal money changer - which SO unfortunately left him with no proof he changed any cash so we only know he was alone with the Taxi driver for 45mins whilst Anni was at the pool on the day of the murder
and we have no proof what they were doing.
I have posted detailed information about Cape Town airport - way beyond the knowledge of a tourist, because my husband flew so much I also spent hours every week parked outside with the taxi drivers and at various times parked my car in the carpark - so know that's how far you have to go to find an illegal taxi - hired cars, took hotel shuttles and jumped in taxis.
I have posted an interactive Google Map which marks out the key points on Anni's last journey, with a picture of each place and a description.
I have given detailed descriptions of what, as a resident of Cape Town, the local perception of that Township, area is and given the gauge that I, as someone not afraid to travel alone all over South Africa including through other townships, would not want to go to that one even accompanied by armed ex-special forces friends. I have made the analogy of it being like staying at the Savoy but ignoring London nightlife and going to look at something like Elephant and Castle, but at the distance of Brighton, to give a proper idea of the likelihood of someone wanting to do it, and I have posted a photo of the route from the airport to show Anni would have seen what Townships looked like before she set out in a sparkly cocktail dress that evening allegedly to visit one.
I have given links and pictures of MZOLI's so you can gauge for yourself whether Anni was in fact dressed in anticipation of visiting a roadside Barbecue.
I have expanded your knowledge of the culture and history of South Africa so will understand just how uneducated and unsophisticated the bottom of the pile is to show you who had the upper hand when it came to scheming, lying and deceiving people because it really is unlikely a man like Tongo has manipulated a man like Dewani and not the other way round.
I have shared my experiences of conducting business in South Africa to show how dishonest the whole lot are, so there is nothing unusual about the other 3 constantly changing their stories.
But you don't reply to any of these hugely informative posts: you just label them as 'tourist information' and ignore them then refer people back to your blog and insist the only evidence that counts is what was said in court. You dismiss everything that was not in court, even though your own blog elaborately weaves a highly subjective story.
