It is certainly curious that a manamba tomato-seller managed to take out 4 people with just 4 clean shots. But who knows ... maybe the guys is just really gifted, or he gets a lot of target practice in good "simulated real-life" environments.
There also seems to be the notion that the arrested people have actually been charged in court. Is that really so? I'd be keen to know more details on that one. In the normal course of things, once they are charged there has to be a hearing on bail, and the coppers would have to state in court what they actually have---as opposed to media stories from "detectives familiar with the investigation" and "police sources who cannot be named because they are not authorized to speak to the media". And if they have not been charged yet, why not?
Last year, in the Mpeketoni case, the coppers acted quickly, and a governor was arrested for "mass murder and terrorism". The police asked that he be held "while investigations continue"; the judge turned them down. (Too bad for this lot that they are not Big People.) Anyways ... month and month after that, the police would come to court and state that "the investigations are continuing". Eventually, the judge said the court aspect of the matter had to be closed and would the police please return when they had completed their investigations. The police never returned, and everyone accepted Mpeketoni and moved on. To this date unanswered questions remain: who did it? where are they? why hasn't something been done to/about them?
So, until I see people charged in court, and a trial underway, I'm going to take with a grain of salt all these stories about "Kenyan Sniper" tomato-sellers.
