Terrorism: the strange case of Kenya

A few days ago, the American government issued a travel advisory warning its citizens to keep away from Kenya because of the "terrorist" attacks that have plagued the country. I understand America's concern because terrorists are not to be trifled with. What worries me is the failure by everyone concerned to notice how odd these "terrorists" are. 
What kind of terrorist stages an attack and doesn't claim responsibility? Your guess is as good as mine. Terrorists are people who want to arm twist society into bending to their whims through threats of violence. They always have an agenda. The irregular thing about our attacks is that no one has come out to claim responsibility. You could argue that they might be lone rangers but what does that say about our security organs? Worse still, what does it say about the mind state of Kenyans? Do we have that many people that are willing to randomly throw grenades into churches? Do we have that many deranged people living among us? If it is so, I am moving to Canada.
Terrorists are also known to execute attacks against targets that ensure maximum casualties and damage; usually iconic buildings or government installations. No offence to the victims but who the fuck bombs a single floor building with 30 occupants while ignoring a 10 storey university building right next to his/her "target?" Going by the security checks we have in most buildings in this city, accessing any building would be easier than picking your teeth after a meal. I suspect someone or some people are being mischievous.
The reaction of the government has been equally baffling. While act of terror are usually followed by increased interrogations, police and/or military presence, conclusive investigations and more aggressive preventive measures, the Kenyan situation is different. No government official has created any plan to be used in the aftermath of an attack or even told us who is executing the attacks. Is it a case of the usual complacency and incompetence of our government or is someone being a smartass and trying to start a conflict between certain groups? Remember how Kenyans wantonly attacked Jamia Mosque after the al Faisal incident? There a storm coming that the weatherman won't predict, best buy your umbrellas now.
