Advertisements that Lie

There are endless examples of advertisements that just straight up lied. We see them all the time and might not even realize it. They are all around us. In other words, we are lied to every day.
Vitamin water claims it is healthy, but it contains as much sugar as coke. They advertise their product pretending it is something it's not, and people believe it. Many times people do not know enough about something to know if it is true.
Eclipse gum claims it will kill the germs that cause bad breath, when the only thing that comes close to killing germs in your mouth is mouthwash. In fact, no gum can actually kill germs; they can only mask it with a good smell.
Many weight loss-related products leave out the fact that you have to exercise to lose weight. It seems like an obvious thing to consider, but there are people that expect results only by eating the food provided by these programs. The programs do not technically lie, but they make it seem like they require less effort than they actually do. Some people will threaten to sue companies that do not tell the whole truth. These people usually end up losing because companies and advertising firms have lawyers to make sure their advertisements are not breaking any rules or laws, even if they found a way to word something so that it tricks people.
Several car crash test commercials show cars that are secretly reinforced with beams to survive the impact. They claim the cars can survive a certain amount of impact and show a demonstration with enhanced impact survival capabilities. The cars shown in the commercials are not what is sold to the public. This is absolutely false advertising because people do not get what was promised.
One specific example of false advertising is s phone commercial that shows off a Nokia phone's camera. The footage demonstrating the camera's features was not actually filmed with that phone. This advertisement shows two people riding bicycles down the road. The man in the commercial is filming the woman using the new lighting features of the Nokia phone. During the video, the background reveals a reflective surface that the real cameraman can be noticed in. Many viewers noticed this mistake and it went viral, making the Nokia company look extremely insincere. Perhaps they should have filmed the video with a Nokia phone like they advertised they would do. Or at least they should not have made the mistake of accidentally showing the real camera:

Really..???

What does Nokia expect people to say when the camera does not work as well as it does in the commercial?
Perhaps someone bought the phone and threatened to sue. Unfortunately, they probably will not win.
Not enough advertisers get in trouble with the law when they lie in advertisements. Why is this a problem?
When something is not as it was advertised, customers are extremely inconvenienced and possibly wasted a lot of their money. No one should be worried about the fact that the product they bought might not be what was advertised.
