Human rights groups have condemned an order by Kenya's internal security minister for police to shoot to kill anyone found with illegal firearms.
Nairobi has a reputation for rampant crime
Kenya's Human Rights Commission said John Michuki's directive would not solve the problems of insecurity.
The Law Society described it as "ill-advised and unconstitutional".
Mr Michuki made his comments in the capital, Nairobi, which has such a reputation for crime residents have called it "Nairobbery".
"We are concerned about the wave of criminal activity that has shot up," the Daily Nation newspaper quotes Khelef Khalifa from the Kenya National Commission on Human Rights as saying.
"And we decry the deplorable state of security in the country, [but] the shoot-to-kill policy is not the answer."
Tom Ojienda, head of Kenya's Law Society, told the East African Standard that under the constitution a person is presumed innocent until proven guilty.
"The minister cannot purport to be protecting lives of Kenyans while on the other hand giving police orders to execute others," he said.
Mr Michuki issued the order on Monday and said he would resign if he could not bring security to Kenya.
"This is a cross I must carry... If I am defeated, I will write a resignation letter," he said, the Standard reports.
Mr Michuki was appointed five weeks ago following allegations of corruption in the security minister.
