The mainstream media regularly manipulate the news. They do the same with pictures, as we have already pointed out earlier here and here.
Below is another example. On 23 April, two weeks after the murder of 17-year old Joe Van Holsbeeck by an illegal immigrant in Brussels Central Station, 80,000 people marched in a silent protest demonstration through the streets of Brussels. People laid flowers at the entrance of the Central Station. The following day this photo, by the French press agency AFP, was published in Het Laatste Nieuws, Belgium's largest newspaper. The empty spaces had been filled up. Why? Evidently not (as with royal visits in Belgium) because there were not enough people.
