But he's a very unusual protester - a former Mossad spy who never before questioned the state for which he once risked his life on foreign missions.
Amir, who declined to be fully named due to his sensitive previous secret roles, is among former veterans of Mossad, Israel's foreign intelligence service, who are taking to the streets in protest at their government's judiciary overhaul.
Reuters spoke with two other former Mossad officials who are also involved in the protests and more fearful of the impact the legislation will have on Israel's security system.
Yossi Cohen, another former Mossad chief, spoke of his concerns for "Israel's immediate national security".
"At a time when the Iranian threat looms over us from multiple fronts, we must ensure Israel's security remains unharmed," Cohen wrote in a July 23 commentary in the Yedioth Ahronoth daily.
