In the Kenyan capital Nairobi, the newspapers are awash with headlines about the college massacre. <br /><br /> People are calling for tolerance and unity, after al-Shabaab militants stormed Garissa University College and killed at least 147 people. <br /><br /> But there is also a feeling in Nairobi that the government could have done more to prevent the bloodshed.<br /><br /> “It is very sad. I really do not understand why al-Shabaab are targeting us. We are their neighbours,” said one man.<br /><br /> “We should be helping each other but instead they are destroying our environment. Not giving us peace and taking our country backwards.”<br /><br /> Another man said: “It’s reached a point where the security agencies give out information, but the police themselves are unable to protect us as they are supposed to. It means someone is sleeping while on duty.”<br /><br /> There were warnings last week that an attack on a university was imminent. A fact that makes it all the harder for the scores of mourners now left praying for the dead.
