Abdel-Fattah el-Sissi spoke at a ceremony marking Police Day, which falls on Jan. 25, the day the uprising began five years ago.
He awarded medals to the families of nearly 40 policemen killed in militant attacks, including eight generals and three colonels. Most of the widows received the medals while accompanied by their children, including infants.
El-Sissi, his eyes frequently welling up, carried the infants, hugged and kissed older children and posed with them for photos.
"The security and stability of nations are not to be toyed with," he said, adding that the security of Egypt was the responsibility of all Egyptians, not just the police and the army.

El-Sissi, who as military chief overthrew in 2013 Islamist President Mohammed Morsi, has presided over a sweeping crackdown on dissent, jailing thousands of Islamists and scores of secular, pro-democracy activists who fuelled the 2011 uprising. He was elected to office in 2014 with a landslide.
However, some of el-Sissi's supporters in the media and in politics have taken to publicly vilifying the 2011 uprising as an attempt by foreign powers to weaken Egypt through local saboteurs.
The president spoke a day after the army said it would beef up security measures to safeguard vital installations and "confront any attempt to violate the law, impact the nation's security and stability." The announcement came amid an ongoing crackdown on dissent ahead of Monday's anniversary.
