Actually the news is praising the cyclist in the video. It also says he rode away after the incident. For your interest, the pedestrian who attacks the downed robbers near the end is the hotel security guard.

Also, the report quote above states that those people are sentenced to death for crimes related to unrest during which over 200 people were killed. It does not say that they are sentenced to death for protesting. It is more likely that they are guilty of murder. Nice combination of biased news writing and poor reading comprehension (sadly prevelant).
