Technically, gatherings of less than 500 people do not need a permit in that park, while having a vigil even in front of the Kenyan embassy or in another commercial place would require cumbersome bureaucracy. 
Kiutaratibu, kukusanyika watu wasiozidi 500 kwenye viwanja hivyo hakuhitaji ruhusa, wakati kuwa na ibada ya kumbukumbu hata mbele ya ubalozi wa Kenya au kwenye eneo lolote la kibiashara kunahitaji kufuata urasimu mkubwa.
